Power balance control method based on D-STATCOM in coal mine power supply system

  • 摘要: 为了解决煤矿供电系统三相不对称运行问题,提出了一种基于D-STATCOM瞬时功率平衡补偿的控制策略。给出了D-STATCOM系统接线图,分析了电网功率不对称对D-STATCOM控制特性的影响。提出了一种单相P-Q功率解耦控制方法,实现电网有功功率和无功功率的独立控制。在此基础上提出了一种零序能量转换为有功功率补偿的机制,给出了一种三相功率平衡的控制方法。Matlab/Simulink仿真结果表明,电网功率不对称运行时,D-STATCOM不但能够独立控制无功功率功率,还可以平衡三相有功电流。
    Abstract: To solve the three-phrase unbalanced operation of coal mine power supply system, a power balance control strategy of D-STATCOM was proposed.It proposed a D-STATCOM system connection diagram and analyzed the effects of power asymmetry on the D-STATCOM control characteristics.To realize theP-Q independent control of active power and reactive power, it mentioned a single-phase power decoupling control method.Through zero sequence voltage injection, it advanced a kind of energy conversion mechanism between zero sequence and active power.Matlab/Simulink simulation results show that during the three-phrase unbalanced operation of coal mine power supply system, not only can the D-STATCOM control the reactive power independently, but also balance the three-phase active current operation.
