On October 22, the 2021 Green Development Skills Competition for Employees of Coal-fired Power Generation Enterprises in Hubei Province, sponsored by the Hubei Federation of Trade Unions and organized by The Hubei Company of CHN ENERGY, successfully concluded. The competition with the theme of "pollution control, emission reduction and increase benefits, green development I first", after layer upon layer of selection, a total of 14 power generation enterprises 101 employees finalists, relay protection, chemical analysis, coal mining and production of the three major competition projects, in the form of "theoretical written test + practice" fierce competition.

Based on years of experience in supporting electrical industry events, HAOMAI ELECTRIC was invited as the technical support of relay protection competition project, providing 6-phase Protection Relay Test System RELAYSTAR-1600 and Dual-channel Circuit Breaker Simulator WDS-2, and appointed technical experts as a third party referee to assist the organizers in the actual operation of the competition part of the referee.

Relay protection work in the power industry is difficult and requires a wide range of knowledge. In the work, it is necessary to deal with different emergencies and deal with them quickly, which especially tests the professional skill level and carefulness of workers. The relay protection operation designated after the 6-phase Protection Relay Test System RELAYSTAR-1600 as a debugging tool, the project is divided into fault analysis and judgment, transmission group protection device calibration and troubleshooting, bus(or line) protection device calibration and troubleshooting. Following RELAYSTAR-1600 is 6U6I type full function high-power protection relay testing instrument, built-in high-performance industrial computer, 12 channels output at the same time, can perform AC test, state sequence, differential protection, line protection, group, distance, zero sequence protection and other tests, which become the first-class equipment of protection relay testing industry.

The participation in the event work, HAOMAI ELECTRIC with professional technical team, excellent comprehensive equipment testing functions, successfully completed all tasks, the host unit and the unanimous recognition of the competitors, we will make unremitting efforts to accumulate experience, do our best to do a good job in the power testing industry.
