为提高电网的功率因数和补偿电网的无功分量,采用了静止同步补偿器(STATCOM),该补偿器不仅能根据电网无功电流变化来实时检测和补偿电网中的无功电流,而且能使电网的电流相位和电压相位保持一致.重点分析了 STATCOM 的核心算法,提出了基于 d-q 变换的直接电流控制方式,并在 MATLAB 工具中对 STATCOM进行了系统的仿真研究.研究结果表明:在给定的条件下,STATCOM 保持了电网的电流和电压相位一致,提高了电网功率因数.该补偿器的直接电流控制方式响应速度快,可以很好地补偿电网的无功,提高电网的功率因数.

@@@@In order to improve the grid power factor and compensate for reactive power, this paper adopts a static synchronous compensator (STATCOM), which can not only detect and compensate for reactive current according to the real-time change of grid reactive current, but also maintain the current phase and voltage phase of grid consistent. The paper focuses on studying the core algorithm of STATCOM, proposes a mode of direct current control based on d-q transformation, and conducts a systematic STATCOM simulation using MATLAB tools. The study result shows that STATCOM maintains the current phase and voltage phase of power grid consistent and improves the power factor of power grid under given conditions. The direct current control mode of the STATCOM has fast response, good reactive power compensation advantages, which improve the grid power factor.
