适应高比例光伏接入的有源配电网改进型故障保护策略
Improved fault protection strategy for active distribution networks adapting to high proportion photovoltaic access
摘要
Abstract
With a large number of photovoltaic(PV)access,the traditional distribution network has changed from a single power source to a multi-source structure.There is intermittence and uncertainty in PV,and it is easy to have the problem of false tripping in current protection when using traditional setting strategy.By the output characteristics of PV and actual measurement data,typical scenario data sets are generated based on the generative adversarial network(GAN)algorithm,and different fault scenarios are constructed.An improved current protection strategy is proposed to adjust the current protection setting coefficient in real time.The active distribution network model is built and compared with the traditional current protection strategy under 3 working conditions It can be seen from the example simulation:The overall false tripping rate of the proposed strategy is reduced by 25%,which is more advantageous than the traditional current protection.关键词
