摘　　要：安全校核是保障电网稳定运行的一道重要安全防线。基于智能电网调度控制系统的服务总线和并行计算服务,研究实现了面向服务的安全校核功能,为日前计划编制、日内计划调整、电网调度操作提供可定制的支持多任务并行的安全校核服务。计划潮流生成是安全校核的基础,结合中国电网分级调度的运行模式提出了基于多断面潮流控制技术的计划潮流算法,并应用无功电压自动调整和潮流不收敛智能调整技术提高收敛性和结果合理性。研究了多级调度日前计划联合安全校核的实用化技术,通过计划数据校验和统计技术指标提高了安全校核的实用化水平。Security check is an important link for power system safety.Based on the service bus and parallel computation technology of the smart grid dispatching and control system,service-oriented security check is studied and developed to provide customizable security check service for day-ahead scheduling,schedule adjustment and power grid dispatching operation. Scheduled power flow is the key function in security check.According to the hierarchical dispatching mode of China power grid,a scheduled power flow algorithm based on multi-section power flow control technology is proposed.Voltage and reactive power automatic adj ustment and intelligent adj ustment for non-convergence of power flow are used to improve convergence and rationality.Day-ahead schedule security check for multi-level dispatching is studied.The practicability is enhanced by checking schedule data and counting some technical indices.
