摘　　要：新能源发电系统大规模接入电力系统,会降低电力系统的稳定性、惯性与无功补偿能力。新能源发电系统经由新能源同步电机接入电网能有效发挥新能源发电系统的优势与传统同步发电机的稳定特性,在解决能源危机的同时,还能保持电网的稳定性。介绍了新能源同步电机的拓扑结构,研究了新能源同步电机的无功补偿能力,最后搭建仿真模型进行了验证。仿真结果表明,新能源同步电机在提供电压支撑的同时,还具备出色的无功功率补偿能力。The large-scale integration of new energy generation systems into the power grid has reduced the stability,inertia,and reactive power compensation capabilities of the power system.By connecting new energy generation systems to the grid through new energy synchronous generators,the advantages of both new energy generation systems and traditional synchronous generators can be combined.This approach can address the energy crisis without compromising grid stability.This paper introduces the topology of new energy synchronous generators,studies their reactive power compensation capabilities,and builds a simulation model for verification.The simula-tion results show that new energy synchronous generators have voltage support and reactive power compensation capabilities.
