Strategy Research and Demonstration Application of Full Split Phase Reactive Power Compensation

随着电力系统对电能质量的要求越来越高,通过无功功率补偿可以提高电网功率因数、降低线路损耗、改善电压质量,因此对无功补偿装置的经济性、可靠性和精准性提出了更高要求。文章提出的“全分相无功补偿装置”开创性应用智能判据融合控制系统,创新采用了“124888”编码控制逻辑,实现“31档”全分相自动补偿,在补偿方式上能对每一相进行单独补偿,从而达到任一相无功平衡。并通过实例验证该方案的有效性,结果验证了该装置具有响应时间短、补偿精度高的优点。

With the increasing demand for power quality in the power system,reactive power compensation can improve the power factor of the grid,reduce line loss,and improve voltage quality.Therefore,higher requirements are put forward for the economy,reliability,and accuracy of reactive power compensation devices.The groundbreaking application of intelligent criterion fusion control system in the"fully split phase reactive power compensation device"proposed in this article innovatively adopts the"124888"coding control logic to achieve"31 level"full split phase automatic compensation.In the compensation method,each phase can be compensated separately,thus achieving reactive power balance of any phase.And the effectiveness of the scheme was verified through an example,and the results verified that the device has the advantages of short response time and high compensation accuracy.
