摘要
数字式变电站仿真系统太抽象,物理式系统价格又太昂贵,都不能达到理想的仿真效果,针对此情况,提出数字、物理混合仿真的变电站综合自动化培训系统。介绍数字部分和物理部分的结构原理与功能,其中一次信号由潮流计算和短路计算软件产生,二次信号生成系统由联网的微机型继电保护试验测试仪同步产生各个测控点的电流、电压信号提供给真实的测控与继电保护设备。通过学员的培训和实验表明,该仿真系统功能全面,仿真效果良好,价格不高,可应用于变电站运行人员的培训工作。
The substation simulation system based on the software is too abstract, and the physics-based system is too expensive. Aimed at this condition, this paper proposes the digital-physics mixed simulation training system for integrated substation automation. Structure, principle and function of the physical simulated parts and the digital parts are introluced. Among them,the primary signals of the equipments are generated by the power flow and short-circuit calculation software, and through networking microcomputer-based protective relay test device the secondary signals generating system generates synchronously the current and voltage signals of the measurement and control points, which are provided to the real control and protection devices. The experiments and training results indicate that the simulation system with low price has the comprehensive functions, good simulation effects, and could be applied to train the substation workers.
