Embodiment Construction

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0047] In the prior art, the analysis of the test result of the series compensation protection adopts: comparing the message generated by the series compensation protection device with the switch value received by the conventional relay protection tester, and comparing the action behavior of the series compensation protection device. Analysis is carried out to judge the correctness of the protection action. Because the analysis of the test results is very complicated, for the debugging personnel of the series compensation protection device, it is necessary to be familiar with the funct...

Abstract

The invention provides a series compensation protection test result analysis method, device and system. The analysis method comprises: receiving an SOE (Sequence Of Events) message generated by a series compensation protection device when series compensation protection happens according to test current signals; matching the SOE message with an SOE message pre-stored in a database; when the matching succeeds, generating a matching success test result, and determining that the series compensation protection is accurate; and when the matching fails, generating a matching failure test result, and determining that the series compensation protection is inaccurate. When the series compensation protection test result analysis method, device and system are adopted for series compensation protection test, accurate actions of the series compensation protection device under various conditions do not need to be learnt by debugging personnel, and the accuracy of the actions of the series compensation protection device can be easily judged.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a method, device and system for analyzing test results of series compensation protection. Background technique [0002] The series capacitance compensation device is a device applied to the high-voltage power transmission network. Its function is to compensate the inductive reactance of the ultra-high-voltage long-distance transmission line and improve the power transmission efficiency. At present, the series capacitor compensation device is widely used in most domestic 500kV ultra-high voltage transmission lines and 1000kV ultra-high voltage transmission line projects. The series capacitance compensation device is composed of series compensation capacitor, MOV (Metal Oxide Varistor, metal oxide voltage limiter), discharge gap, series compensation platform and other parts. As a primary device independent of the transmission line, the series capacitor compensation devi...
