Abstract

The aim of this paper is to present a communication network emulator based hardware-in-the-loop (HIL) real time test bench. The emulator is used together with Opal-RT simulator to build up the test bench for testing of power system protection applications. The emulator enables us to model and vary new network properties and communication services that can have effect on protection system applications. With the aid of power system protection testing based on IEC 61850, this paper demonstrates how this test bench can be set up. Case studies of how the network emulator can be used to model communication properties and how it has satisfactory performance comparable to practical network switches are presented and discussed. In addition, the flexibility and capabilities of the emulator switch on implementation of router functions for management and control to support IEC 61850 Ethernet network communication have been examined.

实时HIL电力系统保护试验台通信网络建模
本文的目的是提出一种基于通信网络仿真器的半实物实时试验台。该仿真器与Opal-RT仿真器共同构成了电力系统保护应用测试的试验台。仿真器使我们能够模拟和改变新的网络特性和通信服务,这些特性和服务可能对保护系统的应用产生影响。结合基于IEC 61850的电力系统保护试验,阐述了该试验台的搭建方法。本文给出并讨论了如何使用网络仿真器对通信特性进行建模,以及它如何具有与实际网络交换机相当的令人满意的性能。此外,仿真器的灵活性和功能开关实现路由器功能的管理和控制,以支持IEC 61850以太网网络通信进行了检查。
