摘要
因无典型光伏系统无功补偿设计指导,目前工程应用中多对光伏电站无功补偿容量采用粗略估算的方法,此方法易造成补偿不足或设计浪费的不良后果,尤其是对设计精度要求较高的采煤塌陷区光伏电站,会造成较大浪费。为解决这一问题,探讨出一种利用电力网络潮流分析原理对无功补偿容量进行较精确计算的方法。该方法通过对光伏组件满发电及截止发电两种情况下光伏电站各节点无功功率进行计算及分析,综合电网公司对计量点的功率因数要求,可得出无功补偿容量的最优配置方案。以某具体煤矿塌陷区光伏电站项目为例,用文中介绍的方法进行计算和分析,并用PASAP软件进行仿真计算,以验证此方法的合理性。此方法不仅适用于计算采煤塌陷区光伏电站的无功补偿容量,还可作为其他各类型光伏电站无功补偿容量计算的参考和借鉴。
Due to the lack of typical PV system reactive power compensation design guide, the reactive power compensation capacity of PV power station is often estimated roughly in the engineering application at present, which is easy to cause the adverse consequences of insufficient compensation or waste of design especially in coal mining subsidence area PV power station. In order to solve this problem, an accurate calculation method is explored for reactive power compensation capacity based on electric power flow analysis principle. This method, by means of calculating and analyzing the reactive power of each node of PV power station under the conditions of full-load and no-load of PV modules, can obtain an optimal configuration scheme of reactive power compensation capacity by integrating the power factor requirements of the grid. In order to verify the rationality of this method, a PV power station project in a specific coal mine subsidence area is taken as an example, the method is applied for calculation and analysis of the project, and the PASAP software is used for simulation calculation. This method is not only applicable to the calculation of the reactive power compensation capacity of PV power station in coal mining subsidence area, but also as a reference for the calculation of reactive power compensation capacity of other types of PV power plants.
