摘　　要：二次系统仿真是集控站仿真的重要方面。通过与调度员培训仿真(DTS)系统中保护仿真的对比,分析了集控站二次系统仿真的特殊性。在原有DTS系统基础上进行了二次系统仿真的扩展开发。针对保护装置屏的多样性,在数据库建模层面进行了为保证数据库结构稳定性的改进。在图形绘制方面,开发了自动绘图功能以应对大量保护屏图的绘制。在保护仿真方面,根据保护自身的规律将保护的压板仿真、功能仿真和配合仿真进行剥离,以应对压板的复杂多变。现场应用验证了该二次系统仿真的实用性及可扩展性。The protection simulation plays an important role in the centralized control substation （CCS） training system. This paper thoroughly analyzes the different features of CCS protection simulation that contrast with those of the DTS one, The protection simulation is proposed based on expansion of the former DTS. An improved protection model that takes into account the database＇ s stability is presented to satisfy the demand of diversified protection set layout. A new auto-drawing technique is developed for reducing the difficulty in protection set picture drawing. By the detachability of the variable protection switch simulation from other protection simulation, the simulation algorithm can keep the hierarchical structure stable with any complex protection switch set. The practicability and expandability of the protection simulation have been validated by on-thespot implementation.
