An Automated Testing Technology for Intelligent Switches
Intelligent switches are a new type of equipment for digital power grid,and conventional intelligent substation testers cannot meet the detection requirements for the secondary system of intelligent switches.This paper analyzes the architecture composition of the intelligent switch secondary system,studies the communication interfaces and functional logic of each constituent device,proposes test requirements and test schemes for acquisition and execution unit,comprehensive control analysis unit,intelligent circuit breaker,and intelligent knife switch.Moreover,it puts forward detection requirements and schemes for overall performance of intelligent switch secondary system ring network.Based on the detection scheme and interface requirements of the intelligent switch secondary system,a detection platform is designed to meet the individual performance test and system performance test requirements,filling the gap in the detection of intelligent switch secondary system and providing technical support for operation and maintenance of digitalized new-type power system equipment.
