Power plants are an important part of power system, but also directly affect the safety and operation of power systems. In the power plant, the first wiring and the second connection is the important part of the electrical part.
In this design, mainly for the design of a connection. From the main wiring scheme for the electricity to the plant design, from the calculation of short circuit current to the electrical equipment selection and layout of power distribution devices, have done more in detail. Secondary Wiring Zeyi generator relay protection design for the project, on the relay protection setting calculation done a thorough and detailed description.
The design process, considering the economy, reliability and developmental and other factors, the premise of ensuring reliability, and strive to economy. Design specification of the terminology used, symbols are also in full compliance with the current standards set forth in the power industry terms and symbols.
