日发电计划安全校核系统开发与应用

Security Checking System(SCS) for Daily Generation Scheduling

安全校核是推进调度计划精细化管理的重要手段。在分析安全校核需求和功能总体设计基础上,依照数据流转中心、流程控制中心和数据展示中心的3条主线设计,提出基于预测-校正技术的功率平衡方法和计划拓扑分析管理方法,形成日计划潮流,在校核出现越限后采用基于安全约束经济调度(SCED)算法的多时段安全校正调整。实际电网运行结果表明系统计算速度和精度满足安全校核工作要求。

Security is an important approach to promote delicacy management of daily dispatch scheduling. Based on analysis of the needs of security checking and design of overall function, in accordance with three master line design which includs data flow center, process control center and data display center, power balance method and plan topology analysis management method based on predictor-corrector thchenology is proposed to form daily schedule power flow, and implement security correction adjustment based on the security constrained economic dispatch （SCED） algorithnm after out-of-limit. The calculation speed and accuracy of system for security checking is proved by practical example.
