| 中文摘要 | 以江西樟树±2Mvar的配电网静止无功发生器(DSTATCOM)的动态补偿项目为背景,以同步补偿谐波和无功为目的,通过现场电能质量测试分析,提出通过对谐波与无功进行有针对性的重点补偿,以降低DSTATCOM的容量需求。以此为基础,从工程实用性出发,提出一种基于限值判断的DSTATCOM分频协调控制方法,并进行了详细仿真验证。该方法通过实时的限值判断确定无功与各次谐波电流的补偿重点,以基于瞬时无功功率理论的电流检测方法为基础,结合直流侧电压的直接比例积分(PI)控制算法和补偿电流的增量迭代式广义积分控制算法实现基波与各次谐波的分频控制。该方法工程实用性强,可根据不同工况有选择性地分频率解决最为关键的电能质量问题,能够有效降低实际应用中DSTATCOM所需的容量,从而大力提升其性价比,对推广DSTATCOM的应用具有一定的意义。; Based on the dynamic compensation project of �Mvar DSTATCOM in Jiangxi Zhangshu Substation,by analyzing the local power quality performance,a harmonic and reactive power synchronous compensation method is proposed aiming at minimizing the compensation capacity.A frequency dividing coordinated control method for DSTATCOM on the basis of limit values judgment is presented and validated by detailed simulation.The compensation priority between harmonic and reactive power is confirmed by limit values judgment and the theory of instantaneous reactive power is used to detect the reference current.The frequency dividing control of harmonic and fundamental wave is realized by the integration of DC voltage PI control algorithm and incremental iteration approach of compensated current based on generalized integrator.The proposed method has strong applicability and is especially suitable for the use in the hybrid compensation system with limited compensation capacity in different working conditions.It helps to improve the DSTATCOM performance/price ratio,and thus widen its applications. |
