摘　　要：网络传输给智能变电站的数据共享带来了便利,但同时网络压力也给智能变电站的可靠运行带来了风险。因此,分析网络压力产生的原因,研究网络压力的表现形式,对网络环境下保护装置的性能进行测试,显得尤为重要。通过研究网络压力产生的原因及表现形式,提出了一种智能变电站继电保护的网络压力测试方法,并给出了相应的技术要求。通过较为真实地模拟不同网络压力情况下的报文,该方法能够测试保护装置在非订阅广播报文及GOOSE/SV报文网络压力下的动作性能,同时也能全面系统地测试智能变电站继电保护装置在不同类型的订阅报文网络压力环境下的装置性能。为保护装置在智能变电站网络环境下的安全稳定运行奠定了基础。Networking brings advantages of data fully sharing in smart substation, but at the same time, network stress also brings risks of operation safety and reliability. Therefore, to find out the reasons of network stress generated, to research the manifestations of network stress, and to test the performance of protection devices under network stress, are particularly important. By researching the causes and manifestations of network stress, this paper gives a network stress test method of relay protection in smart substation and gives the technical requirements. By simulating the packets under different network stress situation, this test method can test the performance of protection devices during the broadcasting packets network stress and unsubscription GOOSE/SV packets network stress. Also it can test the performance during the subscription packets network stress completely and systemic, which ensures the protection devices operating safe and stable in smart substation network environment.
