Description

ACTIVE MODULE FOR ELECTRIC POWER MANAGEMENT

It describes a module for the management of chargeable measurements, especially electricity, as well as the management of other electrical quantities, co-architecture comprised of three modules, and operating process via proprietary firmware operating system via the module's own hardware or via remote server software.

Electricity managers are electronic devices connected after an electrical meter (mechanical, digital or electro-mechanical) operated by the electrical utility. The managers are mostly for Group A operations, ie, high voltage (over 220V), typically small, medium, large companies and some larger commercial consumers (such as shopping malls and supermarkets).

The architecture of the available solutions is based on a set of ehardware software that perform digital measurement at regular intervals, such measurement generates a data set, or seed, of the electrical quantities used by a particular consumer unit. Such data seed is further processed via hardware controllers and embedded software, this result through a data output, traditionally a serial port or similar wired technology; It is then sent for treatment on servers, typically PC-IBM type microcomputers, for the generation of reports, simulations, charts, and so on, so that the consumer can establish policies for the rational use of electricity previously purchased or contracted from the utility.

Traditional equipment is used primarily for large commercial and industrial users who need to establish optimized parameters for the purchase of electricity and consequent cost savings. As for the final cost, such equipment needs technical specification to enable them to operate at High Voltage, so production costs are high since electrical, mechanical and embedded digital systems are designed to operate in harsh environments (magnetism, voltage, temperature, others). Such technical characteristics exclude the use of such equipment by low voltage consumer units, the so-called Group B, because the high cost makes the use of such equipment and its benefits prohibitive for both; dealers, operations service providers and end users.

As a state of the art, various digital electronic metering equipment can be presented, equipment that also performs management and automation of electric energy measurement.

The object proposed in this report consists of a management and decoupling system and reclosing of electricity by the service provider remotely characterized by its electronic architecture and its operation process.

Said power management system, hereinafter referred to as the "MAG-E" Power Management Activating Module, is made up of three modules: an input module consisting of up to three digital current transducers (CTs) and IC for the analysis of electrical quantities; a central processing and transmission module consisting of at least 1 micro controller with encapsulated memory, digital display (LCD), security hardware, bi-directional data transmission unit and wireless controllers (GPRS, 3G, WIFI, ZIGBEE, others) and wired (PLC, CAN, ETHERNET, SERIAL and others), communication ports, consisting of connectors (expansion inputs) for digital modules (PCIs); and an actuation or cutting module via wulti-phase and multi-wire electro-mechanical element (single phase to three phase, 2 to 4 wires). The equipment is equipped with a proprietary firmware operating system (OS) that allows the operation of services, whether based on hardware (additional software on the firmware itself), and / or via remote server software that sends encrypted commands.

The MAG-E has the advantage of real-time, bi-directional remote management of all electrical majorities, thus enabling it to meet the wide range of declining specifications, whether power utilities and their third parties or end customers.

The advantage of the MAG-E is its integrated design that allows the encapsulation of all hardware and functional components in the same design package, thus complying with current electrical measurement standards and regulations, ease of assembly, maintenance etc.

The advantage of MAG-E is that, when in operation, its programming can be via remote management software, thus allowing the maintenance, updating and installation of new services in the "OS" of the equipment, adding value to users, utilities and their third parties, increasing thus the equipment life cycle and its specification to meet critical customer conditions.

It is MAG-E objective, when installed in several units in the field, to establish an intelligent management network, which as main feature allows the real time management of the installed network acting of the quantity treated by the equipment, for example, via software services installed in the said server module, perform diagnostics, calculations, advanced simulations on the installed network and even the power supply.

The figures presented facilitate the clarification of the invented energy management module.

Figure 4 shows a representation of the logic diagram of the operating system of the invented active power management module, MAG-E, operating in GRID format, ie set of equipment, MAG's-E interconnected with each other;

Figure 5 shows the electronic diagram of the invented equipment.

According to the figures shown, the active power management module MAG-E (4) comprises an input module (1) basically consisting of a signal input sensor and an A / D converter; a processing and transmission module (2) comprising a processing unit (21) consisting of a 'CPU' microcontroller (211) which may be of the RISC type, encapsulated memory (214), 'LCD' type display (212) and hardware, security (213). The active power management module comprises bidirectional data transmission units (22) and wireless commands (221) of type GPRS, 3G, WIFI, ZIGBEE, among others, and also wired (222) of type PLC, CAN, ETHERNET, SERIAL, among others. The active power management module comprises communication doors (23), consisting of connectors (231), such as expansion inputs for transmission digital modules (PCIs). The active power management module comprises control units (24) with a plurality of connection outputs for electric drives (241). The active power management module comprises an actuation module (3) with the cut-off modules (31), electromechanically driven and temotatively disabling the entire power supply process.

As shown in figure 2, the active power management module, MAG-E (4), is connected to the home's power grid and communicates with a server (5) via transmission units (22) or communication port ( 23). This communication can be done via wired protocol such as PLC, CAN, ETHERNET cable or others, or via W1RELESS or other wireless protocol.

The logical process of operation is represented in figure 3, basically consisting of the interconnection of the active power management module (4) in the power grid and in the server PC connected to the internet (5). The active module (4) receives the electric power (401), reads and processes (402) the quantities, makes the circular memory register RAM (403).

Said active power management module (4), MAG-E (4), receives encrypted command "CMD" (501) from the server PC (5). The active power management module (4) verifies the "CMD" (communication and / or command) source authenticity (404) and the software and physical integrity (405), generating an affirmative or negative result or response. If the result of the power module (4) response is affirmative or positive, the active power module (4) performs the desired command (406): "hold state (407)" or "perform power on (408)" or "cut (409)" or "memory read (410)", further displaying on the LCD the message of current consumption and its price in currency. For each case except "memory read (410)", the system generates either a positive "CMD OK" response (411) or a negative "CMD FAILURE" response (412). For all cases performed, the results are again encrypted (413) and sent to the server (5). Server (5) receives (502) the result, creates record (503), and triggers actions (504): either billing (505), or network diagnostics (506), or other (507) operations and services. If the result of response (405) of the active power module (4) is negative, said power module erases (414) all RAM memory, displays on the LCD (212) the message 'MEM = 0' (418) and the System firmware diagnostics (415) failure mode, elects (416) failure mode, and sends (417) the encrypted signal "SOS + Failed Diagnostic Mode". The server (5) receives (508) said "SOS + Failure diagnosed mode" result, creates (509) the signal register, triggers (510) the maintenance / operation action (511) for troubleshooting the presented fault and / or Other actions according to customer's need.

The MAG-E equipment (4) operates in GRlD format relative to the power grid, ie a set of MAG-E network operating equipment. It can be used with interconnections between MAG-Es, or NETWORK, for data exchange, where one or more sc communicate with the server as shown in figure 4, or STANDALONE alone as shown in figure 2. In Stand Alone operation As shown in Figure 2, each MAG-E (4) communicates directly with server (5), regardless of its communication systems, and Server (5) through the internet provides online services to dealers, end users or third parties. . Control of the MAG-Es Network (4) of a given region is performed via the server (5). The NETWORK instance, shown in figure 4, occurs, for example, in a humidified light board. In this condition each MAG-E (4) will communicate with the next MAG-E (4) via a wired network through a card connected to one of the communication ports (23), using the CAN (controlled area network). ) as one of the two-way communication protocols, or even via a wireless protocol, such as a dynamically routed WlFJ network. In this way, all MAG-E (4) interconnected via wired or wireless, transfer the consumption data and also commands to the next MAG-E (4) until the last MAG-E (4) installed. The latter MAG-E (4) communicates with server (5) and transmits the data independently of all networked MAG's-E (4).

Figure 5 shows the electronic diagram of the active energy management module MAG-E (4). The input module (1) is comprised of an input sensor which consists of at least one phase bridge (11, 12 and 13), and neutral bridge (14); Through the electrical biasing of the phase bridge (ll or 12 or 13) the phase (s) voltage will be captured together with the neutral of the neutral bridge (14). The signal passes through the resulting digital transducers (15, 16 and 17), where the current signal is measured and passes through the Voltage Inputs (18, 19 and 20). The signal is sent to the digital analog converter (12), 'A / D'. In the 'A / D' converter (121) analog signal (s) transformations are performed for digital data. The data is taken to the input and output connection (122). The disconnect (122) is connected to a multi-volt source (123) that powers the entire system. Disconnecting (122) the data is sent to the 'CPU' microcontroller (211) of the processing unit (21) which will perform the data processing. The 'CPU' microcontroller 211 performs the processing and storage of data in a circular non-volatile memory 214 in table form; This in turn accumulates the data together with time registers (Hour, Minute, Second, Day, Year), locality (CEP), series (equipment code), electrical quantities (power, current, voltage ...), and the structure Table data can be modified via remote commands sent by the server (5) to perform other services on the MAG-E terminal (s) (4). The stored table, the period's accumulated consumption data, together with the current currency value, is displayed alternately on the 'LCD' display (212). In parallel to this process the iCPU 'microcontroller (211) performs two processes: the physical and logical integrity check of the system. As for physical integrity, via hardware 'security (213)', the 'CPU' microcontroller (211) diagnoses system tampering, and automatically erases all memory consumption data (214) and from the firmware (MAG-E operating system), then sending an SOS signal with the physical integrity failure mode, and yet such signal is displayed on the 'LCD' display (212) in the message format "MEM = O". In case of logic integrity and / or faults the 'CPU' microcontroller (211) proceeds in the same way, sending an "SOS + Failure Mode" signal. Two-way communication can be performed via wired (221) or wireless (222), microwave, GPRS, EDGE, 3G transmission units (22) in the processing and transmission module (2) or via other communication means without wired or wired to the communication ports (23). The MAG-E (4) operates without interruption of the telemetry and / or internet signal in case of wired module in Power Iine communication / broadband Iinecomunication (PLC / BPL) technology. MAG-E (4) sends all consumption data in encrypted format to server (5) and receives commands in the same way. As shown, commands can reprogram tables or calculations, or remotely install firmware updates. Cut / light actuation commands are processed by the 'CPU' microcontroller (211) and drive the actuation module (3) to, for example, cut off the power transmission. The drive is via electrical pulses to the control unit (24) via the 'CMD1' and 'CMD2' and can also send continuous power to 'CMD3' to drive other devices. Upon receiving and / or sending and executing a command the microcontroller 'CPU' (211) returns to the server (5) the successful signal of the corresponding operation or failure mode. The cut-off / drive element is initiated via the 'CMD1' and 'CMD2' pulses for the purpose of cutting or normal transmission of energy (Light) of the consumer unit in question. Since the MAG-E (4) even during the power cut of the consumer unit remains in the on state, to receive commands. In the event of a power outage when the MAG-E (4) is switched on, all memory 'MEM' (214) is archived; At the moment of network connection MAG-E (4) performs all measurement, safety and security processes with server (5) in order to report the failure.
