【 摘 要 】

When disconnected from the power system grid, the steadily working photovoltaic power plants would get into the state of islanding operation. Photovoltaic inverter has the function of preventing islanding operation, and state of art inverter designing all contained such components. However, when a photovoltaic power station was at large scale with numerous photovoltaic inverters, inverters would not perform the desired effect. This the paper propposed a novel detection method, which could effectively prevent islanding operation. The detection method used the characteristics of islanding operation to test whether a photovoltaic power station encounters such state. Experiments showed that the proposed method being accurate and fast, capable of preventing islanding operation of photovoltaic power station.
