2×350MW热电厂电气部分设计
摘要
发电厂是电力系统的重要组成部分, 也直接影响整个电力系统的安全与运行。在发电厂中,一次接线和二次接线都是其电气部分的重要组成部分。
本文为规划4×350MW热电厂的一期工程2×350MW热电厂电气部分设计,通过对拟建火力发电厂的概括以及出线方向来考虑,并通过对负荷资料的分析,从安全性、经济性及可靠性方面考虑,确定了220kV以及厂用电的主接线,然后通过负荷计算及供电范围确定了主变压器台数、容量及型号,同时也确定了厂用变压器的容量及型号。最后,根据最大持续工作电流及短路计算的结果,对高压断路器、隔离开关、母线、绝缘子、穿墙套管、电压互感器、电流互感器进行了选型,从而完成了2×350MW热电厂电气部分设计。

Abstract
Power plant is an important part of power system, but also directly affect the safety and operation of power system. In the power plant, a wiring and the two wiring is the important part of the electrical part.
In this paper, for the planning of 4 × 350MW thermal power plant project phase 2 × 350MW for the electric part of power plant design, to consider the coal-fired power plant and the wire direction of generalization, and through the analysis of load data, from the consideration of safety, economy and reliability, determine the main wiring of electrical 220kV and factory, and then the number, capacity and model of the main transformer is determined by the load calculation and scope of supply, but also determine the factory transformer capacity and models. Finally, according to the calculation of the maximum continuous working current and short circuit of the results, the high-voltage circuit breaker, isolating switch, bus, insulator, bushing, voltage transformer, current transformer is selected, th
pleting the 2 x 350MW power plant electrical design.
