Description of the invention: [Technical field to which the invention pertains] r The present invention relates to a Hcpv power grid-connected system which can be added to Taipower's high-powered electric power system, which has a power flow system and has no system. The voltage is too low, too high, too cut: The HCPV power grid-connected system where the problem occurs.荨 【Prior Art】 With the rise in steel prices and carbon dioxide emissions problems. . Heavy, the promotion of new energy-related industries is increasingly receiving international attention, because it hopes to promote the development of the industry through the new energy industry, and gradually achieve the goal of increasing the proportion of domestic independent energy. Because solar power generation can directly convert Taizhi into electricity, there is no noise and no pollution, and it is directly loved by environmentalists, but its cost is about five times that of general thermal power generation. Therefore, it is far behind wind power generation in promotion. In the year of the year, the increase in the source price prompted the multi-national government to implement various preferential and subsidy programs in particular, and the application of the photovoltaic power generation industry to a rapid growth rate of 38% per year. This year, due to the resurgence of the semiconductor industry, the polycrystalline raw materials used in solar cell and semiconductor component manufacturing began to be out of stock, which made the supply of solar cells in short supply, and the system price did not fall. As a result of this phenomenon, in addition to eroding manufacturers to profit, but also some of the latecomers to form a production-free environment, so the product is highly concentrated in the crystallization of solar energy / also, and the lack of upstream raw materials manufacturers, the future development of Taiwan's solar energy 200917614 industry It is a disadvantageous situation. In summary, due to the current situation: the sun caused no material production. And the ten people ^ easy to produce mu under the limited resources not only have the crisis of exhausting resources, but also solve the problem of insufficient domestic energy, but also can not reduce the greenhouse Efficient gas emissions, &, the general needs of users in the actual use of ', ..., / pay to help gradually build a local servant energy industry and develop next-generation solar cells to use the original materials and Dependence is the main issue for national development.

Quantity, low / service to the effect of gas emissions of carbon dioxide and other issues. The secondary object of the present invention is that parallel connection to the Taipower grid system not only does not increase the amount of current in the Taipower system, but also has a tendency to ease 'so there is no problem such as low system voltage, excessive high and overload. Another object of the invention is that the decentralized direct-current AC converter used by the present invention can automatically stop the mains from jumping off the mains to stop the supply of power during the mains failure or open circuit, so the present invention has The characteristics that prevent the islanding effect from occurring, and thus the production of the invention can contribute to the development of the domestic solar energy industry. In order to achieve the above purpose, the present invention relates to an HCpv power grid-connected system, a first-system comprising at least a parent-current converter group, a control device, a factory step-up transformer, a first protection circuit and a first The second protection circuit is constructed by connecting the power to the HCPV power generation unit by the 11.4 volt (kv) high-voltage power distribution system formed by the installation phase, so that the commercial power is connected in parallel; In the aspect of the present invention, the voltage current signal of the second protection circuit is extracted by the current comparator and the voltage regulator of the first protection circuit, and is insulated by a rolling gas circuit breaker connected in series behind the step-up transformer, thereby The power generated by the provincial HCPV power generation device is sent to the nuclear energy research system by the step-up transformer via the step-up transformer (5) ttoe of
