摘要
介绍了工矿企业供配电系统的特点、静止无功发生器STATCOM的工作原理、基于瞬时无功功率理论的id--i。无功电流检测、七电平正弦逆变电压的生成和电流直接控制方法，利用Matlab／Simulink建立了基波无功功率的检测系统和三级联的STATCOM仿真模型。通过理论分析与仿真结果进行对比，验证了设计方案的可行性和有效性，而且，所涉及的方案能够满足无功功率补偿的实时动态快速补偿的要求。
The characteristics of the power supply and distribution system in mine enterprise,the working principle of STATCOM,id-iq reactive current detection based on the theory of the instantaneous reactive power,the formation of seven-level sine-wave inverter voltage and the control method of direct current are introduced. Then the detection system of fundamental wave reactive power and the simulation model of the three associated STATCOM are created by the use of Matlab/Simulink. The feasibility and effectiveness of the design scheme are verified by the comparison of the simulation results and the theory analysis,and the scheme can meet the need of real-time dynamically fast compensation for reactive power compensation.
