摘　　要：针对现有VQC(电压无功控制)装置普遍存在灵活性差、可靠性不高、效费比低的问题,提出了一种基于微机综合保护测控装置实现变电所电压无功控制的方法。微机综合测控装置通过自带的比较器和可编程逻辑方程实现VQC,具有较高的可靠性和灵活性,节省了投资成本,并通过工程实例验证了该方法的优越性。With regard to problems of low flexibility, low reliability and low cost effectiveness existed on voltage quality control devices, a method is put forward for realization of substation voltage quality control based on the micro-computer integrated protection monitoring device. The micro-computer integrated protection monitoring devices are able to realize the voltage quality control by the built-in comparing units and the programmable logic equation, have higher reliability and flexibility, help save the costs of investment. The advantages of the method have been verified by the actual engineering practice.
