Industry high speed development time, electric power is industrial artery, and the power plant is an important part of power system, but also directly affects the safety and operation of electric power system. In the power plant, a wiring and the two wiring is the important part of the electrical part.
In this design, mainly for the one or two part of the design. A part of the main wiring scheme, generator-transformer group characteristics and selection to the electric power plant equipment layout design was done elaborate description. The two parts is to generator-transformer group ECS design topic of electrical equipment logic to do in-depth and detailed introduction and a brief introduction and over voltage protection and lightning protection design.
China resources Electric power Dengfeng CO., Ltd this project scale of1200MW, mounting2 x660MW supercritical coal-fired turbogenerator and leave expansion. This project is completed, will become the main power plant in China resources Electric power system to power grid safety, economy, stable and reliable operation has an important role in.
According to the original data, the CR Dengfeng power plant electrical part design. Generator transformer group control system is the power of the brain, and stable control system, for generating unit's safety is of particular importance. In order to ensure units in the normal operation, start, stop and under fault conditions, avoid units and ancillary equipment for power plant with disappear and damage, improve plant power supply reliability, reliability, economy, flexibility through comparison, identified the main wiring scheme, thereby determining device, such as a transformer, circuit breaker, isolating switch, wires, transformer and lightning protection facilities, the design is reliable, economical and practical
