摘要 为提高供电系统电能质量,研究了采用基于比例谐振控制算法的无功补偿装置解决电网电能质量问题。详细分析了比例谐振控制算法和无功补偿装置的工作原理,通过在天地王坡煤矿掘进工作面对设备投入前后的电网功率因数、电网电压、电网电流和电网谐波进行测试对比分析,验证了该装置对于提高煤矿井下低压供电系统电能质量、提高功率因数和节能降耗的效果。 The reactive power compensation device based on proportional resonance control algorithm is used to solve the power quality problem of power grid. The proportional resonance control algorithm and the principle of reactive power compensation device are analyzed. Comparison and analysis of power factor,voltage,current and harmonics of power grid before and after equipment input in a mine are carried out,according to the results,the effect of this device on improving the power quality,increasing the power factor and saving energy consumption of low voltage power supply system in coal mine underground is verified.
