Optimization on High Speed Avalanche Test Model for Multiple IEC 61850 Server Simulation

针对站控层主机、远动装置等IEC 61850客户端产品的功能和压力测试,如数百台设备的雪崩并发测试和制造报文规范(MMS)链路容量测试,搭建实际装置环境耗时耗力,只能采用软件仿真方式来实现。首先阐述了多装置的IEC 61850服务器仿真的原理与结构,另外在多IEC 61850服务器仿真系统中采用虚拟机技术和时间片轮转原理实现了雪崩测试模型的优化,可在数十毫秒内成功发送300台装置的1 200个报告服务。研究成果缩短了客户端测试环境的搭建时间,优化了雪崩并发测试的速率,可有效地验证客户端数据库和通信的实时处理能力。

Regarding the functional testing and stress testing for the substation level host and tele-control devices, such as avalanche coneurrent test and MMS link capacity test involving several hundreds of devices, it is very time and effort consuming to build the actual test environment. Therefore the software simulation turns out to be the only way to perform the testing. In this paper, the authors first elaborated the principle and structure of the device server simulation of MMS. Then based on virtual machine technology and the time slice rotation principle in multi-server simulation system, the high speed avalanche test model is optimized, which is capable of sending 1 200 reporting service data for 300 devices successfully within the tens of milliseconds range. The research accomplishments can shorten the time spent on the establishment of the test environment at the client end, optimize the speed of the avalanche concurrent test, and henee effectively verify the client database and the real-time processing capability.
