基于变电站数字物理混合仿真技术的多级联合仿真培训系统

介绍了作者研发的基于变电站数字物理混合仿真技术的多级联合仿真培训系统总体结构、关键技术及实现方法。该系统对变电站内监控系统、保护及测控装置、五防系统等采用现场真实物理设备，而变电站一次设备及其邻近电网采用数字仿真，同时采用电磁暂态与全动态电网联合仿真技术，这样既能详细而真实地反映变电站一次设备的行为，又能逼真地再现大电网各类动态过程对变电站的影响。应用该系统可以进行调度、集控站以及变电站运行人员的联合培训和反事故演习，特别是能够有效提高变电站运行人员实际操作的训练效果，并加强变电站人员的电网概念和全局观念。

A Multilevel Joint Simulation Training System Based on Digital-Physical Hybrid Simulating Technology of Substation

In this paper, the architecture, key technology and implementation approach of a multilevel joint simulation training system, which has been developed by the authors, with digital-physical hybrid simulating of substations are presented. In this system, on-site real physical equipments within substation, such as the monitoring system, protective devices, measuring-controlling devices and anti-error-locking devices are adopted while the primary equipments within substation and electric power network adjacent to the substation is implemented by digital simulation; meanwhile, the overall dynamic simulation technology joint with electric magnetic transient simulation of electric power network is adopted, thus behaviors of primary equipments in substation can be simulated actually and in detail, and the impacts on the substation can reappear by various dynamic processes in large scale electric power network. Applying the proposed simulation system, the joint training and anti-accident exercises for dispatchers and operators of centralized control stations and substations can be carried out, especially, the training effect to substation operators' operation of can be effectively improved, and substation operators' conceptions on electric power network, can be strengthened.
