摘　　要：由于国内电网网架结构比较薄弱的特点以及当前日发电计划的安全校核和校正的需求,决定了对发电计划的安全校核及优化调整和阻塞调度等问题研究的必要性。基于此,本文开发了一套日发电计划安全校核及最优调整系统的应用软件,这套系统是由EMS数据接口、数据交互平台、应用服务程序、Web页面4大部分组成。文中利用降阶基方程线性规划法实现发电计划的最优调整,具有自动网络等值、母线负荷预测、实时网络状态读取、分区滚动发电及潮流变化曲线显示、系统图形生成等功能。此系统的开发软件已经在安徽省调度中心投入运行,并由运行结果表明此系统可以有效地实现发电计划安全校核和校正。It is significant to address the issues of security checking and optimal adjustment to daily electric power generation schedules and congestion management in China because of the weakness of the electric power network structures in China and the requirements of the security checking and optimal adjustment to daily generation schedules. This paper presents a software system for security checking and optimal adjustment to the daily electric power generation schedules. The software package consists of an EMS data interface, a data exchange platform, an application server program and a Web page presentation. The optimal generation rescheduling is obtained by using a linear programming algorithm based on the reduced basis technique. This software system is featured as automatic network equivalence, bus load forecasting, real-time network state reading, rolling curve display of generation and power flow and system diagram generation. The developed software system has been applied in Anhui Electric Power Dispatching ＆ Communication Center, and the real-time operations have shown that this system can be used effectively for security checking and adjustment to daily electric power generation schedules.
