In recent years, the state has implemented the "VAT" reform on the sales tax. Therefore, in China, there are many problems in the construction of power grid construction projects in China, therefore, under the new situation, there are many problems in Chinas power grid construction projects.展开更多

The supply of power resources has become an inseparable part of people's daily production and life. Power grid construction has brought many conveniences to people's lives and promoted the economic development of our country. However, there are still many problems in the construction process, especially in the quality management, which will not only affect the economic benefits of power enterprises, but also adversely affect the social benefits. Only by continuously improving the quality management of power projects and keeping pace with the times, can power enterprises always achieve good social and economic benefits.展开更多

The grid is expected to adopt 1000-kV-class AC and ± 800-kV DC transmission systems. In view of significant achievements in technological research and considerable progress in UHV manufacturing technology, China is capable of developing UHV systems. In order to promote the construction of UHV systems,China Electric Power Research Institute and other institutions have initiated first-phase research activities of UHV transmission technologies. The main contents involve research on UHV transmission technology and its economy,developing and manufacturing abilities on UHV equipment, prospective of UHV network frame and selection of demonstration projects, etc.展开更多

It also gradually involves many fields. With the update and iteration of related technologies, many problems are constantly exposed, especially safety management. In the process of electric power construction, enterprises must strengthen the management of electric power line construction to ensure the smooth development of the whole electric power project. In this paper, the problems existing in power line construction and the related contents of safety management countermeasures are discussed, hoping to provide some effective references.展开更多
