What is the work and treatment of Yunnan Power Grid?

Yunnan Power Grid Co., Ltd. was incorporated in Yunnan Administration for Industry and Commerce on June 65438+1October 65438+1October 2000. Legal Representative: Wang Jifeng. The company's business scope includes power production, power supply, power grid operation, wholesale area: administrative area of Yunnan Province, etc.

In April of 20021year, Honghe Shiping Power Supply Bureau of Yunnan Power Grid Co., Ltd. won the title of "Yunnan Province's Advanced Collective for Poverty Alleviation".

The whole power system composed of substations and transmission and distribution lines with various voltages is called power grid. It includes three units: conversion, transmission and distribution. The task of power grid is to transmit and distribute electric energy and change voltage.

China electric power installed capacity, 1.949: 1.85 million kilowatts; 1978 before the reform and opening up: 57120,000 kilowatts; 1987: breakthrough 1 100 million kilowatts; 1995: 200 million kilowatts; 2000: 300 million kilowatts; 2002: 350 million kilowatts; 2003: 390 million kilowatts; 2004: 440 million kilowatts; 2005: 5170,000 kilowatts; 2006: 622 million kilowatts; 2007: 7130,000 kilowatts; From 2002 to 2007, the installed capacity of new power generation was equivalent to the sum of the past 53 years.

In recent years, with the accelerating pace of China's electric power development, China power grid has also developed rapidly, the operating voltage level of the power grid system has been continuously improved, and the scale of the power grid has also been continuously expanded. China has formed six inter-provincial regional power grids: Northeast Power Grid, North China Power Grid, Central China Power Grid, East China Power Grid, Northwest Power Grid and China Southern Power Grid, and basically formed a complete long-distance transmission power grid.

In 2006, China's power grid construction maintained a relatively high scale, and the national power grid construction completed an investment of 2 10575 billion yuan, an increase of nearly 38%. In 2006, with the commissioning of a number of projects to transmit electricity from the west to the east, the cumulative transmission capacity of three channels to transmit electricity from china xd to the east has reached 34 million kilowatts.
