摘要
为改善配电网无功补偿协同优化既有系统和既有算法存在的不足,提出一种配电网无功补偿协同混合算法。在微网控制FDDI网络应用下,实现自动投切无功补偿系统的投切策略PLC并网,在传统算法基础上增加了动作抑制算法和动作延迟算法,确保每次仅有一套自动投切无功补偿设备动作,避免出现过调现象。测试发现,优化后算法与传统算法相比,虽然系统第一次无功补偿较传统系统延迟了42 ms,但在较大无功功率扰动情况下,可以避免系统过调,实现无功功率的快速补偿。
In order to improve the shortcomings of existing systems and algorithms for collaborative optimization of reactive power compensation in distribution networks, a hybrid algorithm for collaborative optimization of reactive power compensation in distribution networks is proposed. Under the application of micro grid control FDDI network, the automatic switching strategy of reactive power compensation system PLC grid connection is realized. On the basis of the traditional algorithm, the action inhibition algorithm and action delay algorithm are added to ensure that only one set of automatic switching reactive power compensation equipment acts each time to avoid overshoot. The test shows that, compared with the traditional algorithm, the optimized algorithm can avoid system overshoot and realize rapid reactive power compensation in the case of large reactive power disturbance, although the first reactive power compensation of the system is more than twice as long as the traditional dissemination delay, and the first reactive power compensation takes more than 42 milliseconds.
