文档介绍：企业供电系统的综合保护的设计
摘要
电力是现代企业的主要能源和动力,是现代文明的物质技术的基础。没有电力就没有企业的生产经营。如果电力突然中断,就会对企业造成不可估量的损失。所以本文就针对企业供电系统的计算机综合保护进行了设计。
本文通过对企业用电设备的功率及其分布的分析,并利用需要系数法进行负荷计算完成了一次配电系统的设计。根据用户需求和供电设计规范,确定了企业供电系统的计算机综合保护的设计方案。该方案完成了企业供电系统的PT保护,过电流保护,欠压保护,过载保护,信号指示以及供电系统的运行监控。采用计算机综合保护方案来保护企业的供电系统,极大的简化了变电所的二次接线,缩小变电所的占地面积,节约了投资,提高了供电系统的安全性与可靠性。

The enterprise of the power supply system prehensive protection design
Abstract
Electricity is the main energy and power of the modern enterprises, and also the foundation of the material technology of the modern civilization. Where there is no electricity, there is no production and management of the enterprises. If the electricity was suddenly interrupted, this would result in incalculable losses of the enterprise. So in this paper, the program puter’s integrated protection has been designed to protect supply system of the enterprise.
This paper pleted the design of supply system by analyzing the electrical device’s power and distribution, and also by using needful-coefficient method to load calculation. According to needs of the user and the specifications of supply system, it has identified the plan puter’s integrated protection, which is used to protect supply system of the enterprise. In this plan, we can achieve the PT’s protection and the lines’ safety when the current is over the standard, or the voltage is under the standard, or the lines are loaded too many devices, and also the operational monitoring of the supply system. The supply system which is protected by puter’s integrated plan has greatly simplified the substation’s secondary wiring, reduced the area of the substation, and saved the investment, improved the safety and reliability of the supply system.
