摘　　要：无功是电力系统运行的最大问题,不仅耗费大量的电能,还会增加电网的发热,增加能源消耗,给电网带来巨大的经济损失,因此加强电力系统的无功监测是目前亟待解决的问题。目前,电力系统无功监测存在数据量大、数据结构复杂的问题,造成无功监测结果不准确、无功监测时滞等问题,无法为电网潮流调节提供支持。为此,提出一种连续离散化算法,对电力系统进行无功持续监测,并通过离散性分析,判断电力系统的无功信号。MATLAB仿真显示:连续离散化算法准确率达到92%以上,降低了系统资源的占用率,降低幅度达到25%,时滞时间小于0.2 s。与蜂群算法比较,连续离散化算法能满足电力系统无功监测要求。Reactive power is the biggest problem in power system operation.It not only consumes a lot of electric energy,but also increases heat production of the grid,increases energy consumption,and brings huge economic losses.Therefore,strengthening the reactive power monitoring of power system is of greaturgency at present.The reactive power monitoring of power system has the disadvantages of large amount of data and complex data structure,leading to inaccurate reactive power monitoring results,delay of reactive power monitoring,and other problems,and thereby cannot provide satisfactory support for power fluctuation regulation.In this paper,a continuous discretization algorithm is proposed to continuously monitor reactive power,and identify reactive power signal through discretization analysis.MATLAB simulation shows that the continuous discretization algorithm has an accuracy rate of more than 92%,and reduces the occupancy rate of system resources by 25%,with the delay time less than 0.2 s.Compared with the bee colony algorithm,the continuous discretization algorithm can meet the requirements of power system reactive power monitoring and reduce the occupation of system resources.
