【摘要】 从面向规划的角度出发,提出了一种基于最大负荷预测的地区电网静态安全分析方法.根据面向规划的静态安全分析的特点,通过对最大负荷预测模型的建立及使用和静态安全分析的方法等进行分析,改进了年最大负荷的取值方法,并结合大量的负荷采样数据,生成了负荷特性曲线库,明确了在此基础上的软件实现方法、结构流程和功能.所开发的软件应用表明,该方法便于发现电力系统的预期网架结构在未来预测负荷水平下的安全隐患,并能辅助使用人员作出合理规划.更多还原

【Abstract】 <Abstrcat>　From the point of view of planning, a maximal load forecasting based security analysis method for district power network is proposed. Here, the feature of planning oriented security analysis, the establishment and use of maximal load forecasting model and the method of security analysis are researched, and the method to acquire the value of annual peak load is improved Based on a lot of sampled load data,a warehouse of load characteristics is formed, on the basis of which the realization method of this software, its architecture and flow chart and functions are determined. The applications of the developed software show that by using the proposed security planning method,it is convenient for the anticipate district power network structure to discover the hidden trouble of system security under forecasted future load level and to assist the user to work out reasonable planning.更多还原
