摘    要:静止无功发生器受光照强度等环境影响比较大,导致其输出功率不稳定。根据逆变主电路的结构特点,提出将静止同步补偿器与光伏发电系统和飞轮储能相结合的新型系统,该系统在向电网输送电能的同时能够补偿无功和抑制谐波。仿真和实验验证该方案能提高系统的供电能力和供电质量。

Abstract: Power system is susceptible to light intensity and other environmental factors, which results in the unstable output power. According to the structure characteristics of inverter main circuit, a new power system composed of STATCOM, photovoltaic and fly storage was proposed. In this system, the transmission power can compensate for reactive power and suppress harmonics when the system supplies electric energy to power grid. Simulation and experiment results show that the proposed scheme can improve ability and quality power supply of the system.
