Auxiliary service security checking method based on static security domain

The invention discloses an auxiliary service security checking method based on a static security domain. The method comprises the following steps: step 1, acquiring a generator operation state according to a topological structure and parameters of a specified power system and an active output upper limit and an active output lower limit of system nodes; 2, establishing a power system auxiliary service safety model according to the operation state of the generator; 3, checking the auxiliary service security model of the circuit system in an off-line mode, if conditions are met, outputting a standby thermal stability security domain, and otherwise, returning to the step 2; according to the invention, scheduling personnel and a power plant can conveniently and reasonably formulate an electric energy and standby auxiliary service scheduling output scheme. 本发明公开了一种基于静态安全域的辅助服务安全校核方法，包括；步骤1：根据指定电力系统的拓扑结构和参数、以及系统节点的有功出力上限、有功出力下限获取发电机运行状态；步骤2：根据发电机运行状态建立电力系统辅助服务安全模型；步骤3：采用离线方式对所述电路系统辅助服务安全模型进行校核，如果满足条件，则输出备用的热稳定安全域，否
