Design and Implementation of a One-click Sequence Control Tester Based on Closed Loop Verification
Due to lack of effective means to verify sequence control logic,current sequence control tests during substation deployment only involve the verification of a certain function using testing equipment or software according to engineering needs,and require the cooperation of bay level IEDs or scheduling master stations.This results in complex testing environment,low test efficiency,and a certain degree of subjectivity,which is not conducive to rapid deployment and application of sequence control.In order to solve the above problems,this paper proposes a one-click sequence control tester based on closed-loop verification.The tester is designed to be capable of performing simulation on operation tickets retrieval,rehearsal and execution from the perspective of scheduling master station,and also on response to operational instructions with respect to actual station equipment.Therefore it may be useful in facilitating the construction of closed-loop verification scenario,the completion of logical verification of sequence control operation tickets,and effective reduction in time consumption for initializing sequence control.
