Abstract

The invention relates to a closed loop testing device and a closed loop testing method of a turbine security monitoring and protection system. The closed loop testing device of the turbine security monitoring and protection system comprises a processor, a voltage output module, an on-off input module and an analog input module, wherein the voltage output module is controlled by the processor to output a specific simulation signal to an on-site TSI system; the TSI system is used for generating a corresponding protection signal according to the received simulation signal; the protection signal output by the TSI system is further fed back to the processor of the closed loop testing device, and thus a closed testing loop can be formed. By adopting the closed loop testing device of the turbine security monitoring and protection system, closed loop tests on the TSI system can be achieved, the clamp measurement and output precision, the clamp protection value and parameter setup, internal wiring and the like of the TSI system can be comprehensively tested, the reliability, the accuracy and the security of the turbine security monitoring and protection system can be ensured, and a great significance for maintaining safe operation of a machine set can be achieved.

Description

technical field [0001] The invention relates to a closed-loop testing device and method of a steam turbine safety monitoring and protection system, belonging to the technical field of steam turbine safety monitoring and protection system testing. Background technique [0002] The steam turbine safety monitoring and protection system (TSI) is the most important safety system of the steam turbine. Its reliability, accuracy and safety are directly related to the safe operation of the whole unit. However, due to the lack of testing equipment, it is difficult for on-site technicians to It is tested that once a safety accident occurs in the steam turbine safety monitoring and protection system (TSI), it will not only cause huge economic losses to power generation enterprises, but also affect the safety of power grid operation. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a closed-loop testing device for the safety monitoring and protection...
