摘要:
继电保护装置的定值和各项性能指标是在离线状态下根据系统的最大运行方式和最小运行方式获得的，在系统运行中保持不变。但是，在系统实际运行中，其运行方式是在不断变化的。当系统处于某些特殊的运行状态时，系统中部分保护的定值可能不能满足灵敏度和选择性的要求，存在保护误动作的事故隐患。如果不能及时发现并进行调整，可能会造成大范围的停电事故；因此，对系统定值进行实时校验是非常必要的。本文对基于SG-OSS平台的在线校核应用进行研究，主要有在线校核的基本功能、主要的设计方案、综合数据模型的形成分析以及对核心算法——并行计算的探索。The setting value of relay protection and the performance index are attained in offline mode ac-cording to the maximum operating mode and minimum operation ways, and remain unchanged in the operation of the system. However, in the actual operation of the system, its mode of operation is constantly changing. When the system is in some special operation conditions, partial protection system in the fixed value may not satisfy the sensitivity and selectivity of the existing requirements, the protection disoperation accident may occur. If you can’t find and adjust it, it may cause widespread power outages; therefore, it is very necessary to do real-time check for the system setting. This paper studies online check application based on SG-OSS platform, introduces the formation analysis of basic function, online check of the design scheme, main integrated data model and introduces the calculation of the core algorithms, parallel computing.
