Testing system and testing method of complete machine safety system of generator unit

Abstract

The invention discloses a testing system of a complete machine safety system of a generator unit. The system comprises a safe signal access mechanism and a safe logical testing mechanism, wherein thesafe signal access mechanism comprises a branching terminal and cable connected with the branching terminal, the branching terminal is arranged a safe system input and output cable to acquire input and output signals of a safe system; the safe logic testing mechanism comprises a signal acquisition unit and a safe logic judgement unit connected with the signal acquisition unit, the safe logic judgement unit is used for receiving a signal transmitted by the signal acquisition unit and judges whether logical relation of received input and output signals of the safe system is correct according tostorage information in a database to obtain a fault position and corresponding maintenance advice of the safe system. The invention discloses a testing method of the complete machine safety system ofthe generator unit. Testing procedures of the safe system can be rapidly and automatically completed, the fault position of the safe system can be positioned, corresponding maintenance advice and operation advice can also be provided, and a testing result is timely, accurate, comprehensive and reliable.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a test system and a test method for a complete safety system of a generating set. Background technique [0002] The safety system of the generator set is also called a safety chain in this field, which connects the fault points that cause fatal damage to the generator set in series. When any of these fatal fault points is disconnected, the generator set will enter an emergency shutdown To protect the safety of the generator set. [0003] The safety system of the generator set is the last protection of the whole unit. Its functional completeness and effectiveness are related to the safe operation of the whole unit and even the power grid included, so the test link of the safety system is very important. The functionality of the safety system is subjected to a detailed functional test before leaving the factory. The test content includes safety system test and safety log...

AI Technical Summary

Problems solved by technology

However, the existing test process is usually completed by manual control, and different types of generator sets are completed by corresponding technicians. The technology is relatively strong, resulting in different personnel's mastery of the test specifications. Manual operation is also easy to cause observation error and operation error of test results

[0004] This shows that the safety system test of above-mentioned existing generating set still has inconvenience and defect, and urgently needs to be further improved
