1200MW Power Plant The Main Electrical Wiring Design

Power plant is an important part of the power system, but also directly affect the safety and operation of the entire power system. In power plant, an electrical wiring and secondary wiring is an important component of the power plant design. This design mainly for condensing power plant electrical part to carry on the design at a time.The graduation design research of1200MW power plant, the main electrical wiring design, first of all, through the analysis of the main raw material proposed two wiring scheme, by comparing chose a relatively better solution the topic. On the main transformer was determined by the load calculation and range of power sets, capacity and model, but also determines the factory with the capacity of transformer and models; According to the maximum continuous working current and short circuit calculation results, the circuit breakers, isolating switches, busbar, transformers, current transformers, bus, voltage transformer, current transformer, lightning arrester on the selection, at the same time to ensure the reliability of the premise, with economy and flexibility, so as to complete a1200MW power plant, the main electrical wiring design.
