Technical field
The utility model belongs to wind power generation field, relates in particular to a kind of circuit of the driver drives for the wind power AC pitch-controlled system.
Background technology
Wind power generation is a kind of relatively ripe developmental technology of new energy resources that developed, and universal and application is widely arranged.Variable blade control system is one of core component of wind turbine generator, and its Main Function is the size of by changing wind turbine generator blade angle, regulating wind driven generator output power, guarantees that wind-driven generator output is in rated power.Variable pitch driver and change oar motor are the performance elements of variable blade control system, are also one of most crucial parts of pitch-controlled system.At present, the pitch-controlled system of China's wind power generation group adopts DC driver and direct current machine more, and the power density that its ubiquitous problem is direct current machine is little, and cost is high, troublesome maintenance, and the commutation brush is that wear-out part need to regularly replace etc.Especially fall over a large area cost in the wind-powered electricity generation industry, improve today of cost performance, its shortcoming is more outstanding.
Ac motor structure is simple, reliability and durability, cost is low, easy to maintenance, just in time overcome the above-mentioned shortcoming of direct current machine.The application in variable propeller pitch control of ac driver and alternating current machine is more and more extensive.But the working power of ac driver control board is generally all produced by transformer, the transformer input is directly from the bus power taking of driver, and bus is the electric network source rectification by the ac driver input.Wind-powered electricity generation electrical network of low quality caused the EMC risk of working power of ac driver master control borad larger.
The utility model content
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of circuit of the driver drives for the wind power AC pitch-controlled system.
The purpose of this utility model will be achieved by the following technical programs:
A kind of driver drives circuit, comprise transformer, the input of described transformer is connected with the bus of ac driver, and the output of described transformer is connected with the input of one-level power isolation module, and the output of described one-level power isolation module is connected with the ac driver master control borad.
Preferably, above-mentioned driver drives circuit, wherein: also comprise an external dc power, the input of described external dc power is connected with a ups power, and the output of described external dc power is parallel to the output of described transformer by a clamp diode.
The working power of the utility model ac driver master control borad is by the Redundancy Design of isolation and the external dc power power supply of one-level power isolation module, improved the reliability that ac driver is used in the wind power AC pitch-controlled system, function to universal ac driver is increased and is optimized, make ac driver meet the specific (special) requirements of variable pitch driver, application function strengthens, performance improves, and more meets the application requirements in the wind power AC pitch-controlled system.
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
The accompanying drawing explanation
Fig. 1 is the circuit diagram of the utility model embodiment 1.
