新型全数字电力系统仿真与教学实验平台的研制

Experiment Platform of New Type Power System Digital Simulation and Teaching

数字仿真具有安全、经济、方便灵活的优点,在很多方面已逐渐替代物理模拟装置,成为电力系统仿真、实验和培训的主流选择。本文工作涉及一种新型的、具有完全自主知识产权的全数字电力系统仿真与教学实验平台的研制。平台的开放性、扩展性好,系统实验安全,不但可以计算电力系统的电磁和机电暂态过程,实时模拟电网的各种运行状态,而且还能够连接真实的物理装置,进行保护装置、安全自动装置以及测量和控制装置的实时闭环测试。一方面是学员熟悉电力系统及一、二次设备运行状况,完成实验课和毕业设计的仿真平台,另一方面,也为教师进行科研课题研究、技术产品开发提供了理想的试验工具。

Digital simulation has the advantages of safety, economy, convenience and flexibility. In many aspects, it can substitute analogue devices and become the magistral selection for simulating, testing and training works in power system. A kind of power network digital simulation and experiment platform is introduced in this paper, which is newly developed with self-determination knowledge property right. This platform has the characteristic of open and extending. It not only can calculate the electromagnetism and electromechanism transient process, and simulate various operation states of power system in real time, but also can connect the analogue devices, such as protection relay, automation measure and control equipments, for real time close-loop testing. On one hand, it can make much more vivid circumstance for users to understand the performance and characteristic of power network and its automation devices. On the other hand, it provides ideal tools for many works as technology research and products development.
