Embodiment Construction
[0017] A method of safely using line protection devices in wind farms is basically composed of three parts. The first is to establish a real-time simulation model, which has a real-time simulated grid environment including wind turbines; on this basis , the second step is to establish a testing platform for the test system, which includes real-time digital simulation workstations, RTDS real-time digital simulators, analog output boards, power amplifiers, line protection devices, analog circuit breakers, switch conversion devices and digital input boards card; thirdly, on the basis of the operation of the above-mentioned simulation workstation, test and test are carried out according to the test requirements.
[0018] Here, the real-time simulation workstation is a computer management system, which contains a virtual grid environment and a real-time simulation operation model, wherein the virtual grid environment is such as figure 2 As shown, it includes wind farm, busbars L, ...
