摘　　要：分析了煤矿供电系统中无功和谐波电流带来的危害,设计出基于动态无功补偿装置STATCOM的补偿方案,在传统的基于瞬时功率的补偿电流检测方法的基础上,提出了基于基波正序电压检波器的p-q检测法,此种方法能在电网不平衡、畸变等恶劣情况下快速、准确地检测出负载侧的谐波和无功电流分量,电流跟踪采用滞环比较控制,有效地解决了煤矿供电系统复杂的问题。This paper analyzed the harm that reactive and harmonic current brought to the coal- powered system, and devised a set of reactive power compensation device based on STATCOM. By the traditional method of compensation current detection on instantaneous power, this paper proposed p - q detection based on voltage detector of positive sequence. It could measure harmonic and reactive com- ponent of the load in the conditions of power grid imbalanced or distorted quickly and accurately. Using hysteresis comparison control for current tracking can effectively solve the complex problem of the power supply system.
