摘要：为解决目前国内外电气计算方法对规划电网输入参数要求过高的难题，将地块预测负荷转变成电气计算负荷，提出对地块未来负荷进行空间分配的实现方法；并在研究经典可靠性公式的基础上提出综合故障率的概念，给出了更具实用性的可靠性工程计算公式，简化了经典公式的使用条件。将电气一体化计算(含潮流、短路、可靠性及N-1校验)、负荷预测和负荷空间分配等核心算法应用在德州晶华网格化规划项目中，结果表明，该工程化实现方法准确、快速，能满足电网规划工作的需要。
Abstract:In order to solve the problem that the current domestic and foreign electrical calculation methods have too high requirements for the input parameters of the planning power grid, the predicted load of the plot was transformed into the electrical calculation load, and the realization method of spatial distribution of the future load of the plot was proposed. On the basis of studying the classical reliability formula, the concept of comprehensive failure rate was proposed. Moreover, a more practical reliability engineering calculation formula was given, which simplifies the use conditions of the classical formula. The core algorithms of electrical integration calculation (including power flow, short circuit, reliability and N-1 verification), load forecasting and load space allocation algorithm were applied in the grid planning project of Dezhou Jinghua. The results show that the engineering implementation method is accurate and fast, and can meet the needs of power grid planning.
