Zhou Haibin assiduously studied the professional knowledge of power system, set up a standardized reading room, set up a cram school for cultural study, took the lead in passing the advanced skills examination of substation operation, and became the technical backbone of the unit at the earliest. He has participated in various technical contests and competitions on behalf of the unit for four times and won the first prize for four times. He organized everyone to carry out technical discussions and tackle key problems, compiled, revised and improved ten kinds of standardized materials and systems, carefully sorted out and summarized the knowledge and practical operation experience of substation, compiled a systematic computer program and implemented systematic microcomputer management. Five small-scale technical transformation projects have been implemented successively, reducing losses and saving expenses and increasing income by more than 800,000 yuan. In the post of substation operation management, the operation task was carried out for 8800 times, and there was never an illegal operation accident. It has created a good record of more than 12000 times of equipment maintenance without accidents and personal equipment running safely for 6670 days. The equipment integrity rate of the substation under his jurisdiction has increased by more than 1%, and this alone can save more than 50,000 yuan.
