摘要
介绍一种变电站保护系统的通用仿真方案。利用动态连接库（ＤＬＬ）技术，按各保护的保护原理建立保护模型库，以故障计算为基础，以整定值和延时时间为判据，采取提高实时性的有效措施，按时间段扫描全部保护。采用这种方法可使保护仿真的效果既快速又准确，并具有很强的通用性，不仅适用于培训变电站运行人员，还可用于培训保护定检人员。
A universal simulation project for substation protection system is presented in this paper. In this project using dynamic link library technology and according to the principles of various protective devices a protection model library is built. On the basis of the result of fault calculations and taking the setting values and time delay ranges as criterions, the whole protection devices are scanned according to the time interval and the simulation of protective relaying is fast, real time and accurate. This simulating method not only can be used in the training of substation operators, but also in the training of the inspectors of protective devices.
