摘　　要：针对油田生产中潜油电机无功功率的变化和消耗对电网质量、设备性能产生的不利影响,基于瞬时无功功率理论,研究了一种新型改进的无功电流提取算法,将其应用于潜油电机无功补偿系统中。该方法能够在工频下提取基波的正序和负序无功电流,省去了锁相环,完全不受电压畸变和频率的影响。补偿策略采用正序、负序无功电流同步补偿的控制方法。Matlab仿真结果验证了无功补偿系统不仅能满足潜油电机无功动态补偿的要求,还可以有效抑制系统电流的不平衡。Considering the design and application of boiler flue gas sulfur control system in Zhangjiakou Dong- huan Heating Company, and based on the magnesium oxide desulphurization technology, the pH value control in the system was researched and the monitoring signal was reported back to the PLC and compared with the set value, as well as the error value was optimized in the PID control, including the design description of the sys- tem＇ s hardware, configuration, interface and optimization.
