This design is a captive power plant electrical part of the project, the design depth of the preliminary design of electrical main connection, short circuit current calculation, the main shebei conductor xuanze, auxiliary power system layout, UPS DC system power supply design, generator excitation systems, secondary line protection system, system protection systems, over-voltage protection and grounding systems, lighting and maintenance systems, communications systems, such as 15 electrical subsystem design. This project planning three furnace installed two machines, three 410t/h high pressure circulating fluidized bed boiler, two 125MW high pressure steam extraction turbine generator, the current design capacity for the two stoves and one machine, allow expansion of a furnace of a machine’s condition. Electrical main connection with generator-transformer unit connection means to a back outlet access 220kV substation, extension of a unit set aside for a return to qualifying conditions.
