Abstract: RTDS is an effective simulation method for mining and processing the hidden criterion of protection device. Based on the case of invisible criterion blocking line protection under unstable high resistance ground fault, this paper analyzes the test requirements, platform, equipment parameters and test items of modeling and simulation of unstable high resistance ground fault based on RTDS, on the basis of accurately grasping the characteristics of the unstable high resistance ground resistance change. The test results show that the proposed simulation model can accurately fit the characteristics of unstable high resistance ground fault. Based on the summary of the test results, this paper further puts forward engineering suggestions for optimizing the operation performance of the protection device.

Key words: instability, high resistance grounding, RTDS, modeling and simulation test, engineering proposal
