The framework and functions of a security risk prevention and control system for grid dispatch operation are introduced, which integrates the function modules of PAS into the generation procedure of operation order to form a complete solution, including operation sequence generation, security check , regulation check , operation order translation , automatic simulation , security assessment , assistant decision-making and visualization. The regulation check uses fingerprint identification technology to support the operation sequence review by bottom-layer regulations and the atomic-model-based knowledge base is proposed to support the operating language review by top-layer regulations,based on which,the relevant dispatch regulations of Yunnan Power Grid are summarized to form the knowledge rule base for the intelligent check of dispatch operations. Two check schemes are proposed: operation order check and operation sequence check. The latter is recommended.%介绍了一种电网调度操作安全风险防控系统的体系结构和功能构成.该系统以操作票智能校核为中心.把PAS功能模块集成到操作票的开票过程中,形成完整的图上生成操作序列-安全校核-规程校核-翻译成操作指令票-自动模拟-风险评估-辅助决策与可视化展示的完整解决方案.规程校核采用指纹识别技术来支持底层规则对操作序列的校验,提出了基于原子模型的知识库来支持高层规则对操作语句的校验,并以此为基础,对云南电网的相关调度规程进行归纳总结,形成了知识规则库用于调度操作智能校核.提出了2种操作过程的校核方案,一种是在调度员先开出操作票的基础上进行校核的方案,另一种是调度员先生成操作序列,由底层规则校核操作序列开始直至开出操作票的方案.推荐采用后一种方案.
