WYB3T series protection equipment was developed based on mature hardware platform, and its design purpose was to serve as general protection equipment applicable to large generator and transformer unit. It was under research and development in 2005 and completed in 2006, and then passed dynamic simulation test and type test by Research Institute of Electronic Science and Technology and technical review by the experts. Its model machine has been put into industrial trial operation in 300MW unit of Geheyan Plant, which has passed technical review by Three Gorges Corporation and will be applied in Three Gorges Underground Plant.

 

Our company developed WYB-01 series micro-computer generator transformer protection equipment with independent intellectual property in 1993, which is also among the first group of manufacturers specializing in protection of micro-computer generator transformer. This equipment was successfully operated in Gezhouba Dam Plant in 1993, and passed national appraisal the next year. Now 21 generator protection equipments of Gezhouba Dam Plant (170MW for 2 sets and 125MW for 19 sets) are all this series products. So far these series micro-computer generator transformer protection products have been applied in such hydraulic power plants of great significance as Gezhouba Dam, Danjiang, Sanmenxia and Yanwoxia.

 

Our company developed WYB-3C multi-branch micro-computer transformer protection equipment with independent intellectual property in 2000, whose differential protection covered more than 8 sides. This equipment was successfully put into operation in the transformer of expanded unit wiring of Gezhouba Dam, and passed product appraisal by Department of Science and Technology. The appraisal conclusion is that this equipment achieved domestic leading level as well as international advanced level. Now the series micro-computer transformer protection equipment has been operated in 500KV transformer of Gezhouba Dam.

 

WYB2000 series protection equipment was developed based on mature hardware platform, and its design purpose was to serve as protection equipment for 100MW and below generators and 110KV and below transformers. It was under research and development in 2004 and completed in 2006, and then passed dynamic simulation test and type test by Research Institute of Electronic Science and Technology. Now the series micro-computer generator transformer protection equipment has been applied in many nationwide plants as Yunnan Mangli Plant, Dimaluo Plant, Sichuan Jiangkou Plant and Guizhou Haili Plant.
