规模化风电场的故障特性对保护影响研究
Study on the protective effect of the fault characteristics of large-scale wind farm
With the wind turbine scale investment, the fault characteristics are very significant, and there is a great difference with the traditional power supply. And now the vast majority of the fan side of the protection or the wind turbine as an ordinary power to configure protection, then it may cause the protection can not be reliable action. So in the event of failure, the fan side of the relay protection can be reliable action is important. The effect of weak wind generation airport on relay protection is particularly prominent, they just did a lot of experiments to illustrate the characteristics of impact and have given but the theoretical basis of relay protection, thus giving theoretical basis to judge whether the recognition of fault protection, reliable fault location, reliable tripping is particularly important. According to the principle of protection of different fault types, gives the theoretical basis, and prove the correctness of the theory in the simulation, and then the wind side protection also gives some reasonable suggestions to make it more reliable.
