Current Status and Development of National Grid in China

With most primary energy resources far from load centers, the voltage level of power system in China has imperatively been upgraded to meet the demand of long-distance power transmission. The successful commissioning of the 750-kV HVAC line in Northwest Power Grid has opened an era of national grid development and brought about a series of technical problems to be faced. This report introduces briefly the current status and policies of UHV development in China.     

Development of PLC Technology in China

In China there built a large scale of power line communication (Abbr. PLC) testing network. This paper presents the research and development on PLC technology in China and also the application and popularization of PLC in Chinese market. At the end, the next focal points of PLC technology research are deeply discussed.     

Practice and Prospect of AC/DC Hybrid Power Grid in Southern China

China Southern Power Grid is a unique EHV AC/DC hybrid transmission network that operates in China. In its service area, the distribution of energy resources and the development of economy are extremely unbalanced, so long-distance and bulk power transmission are needed; besides, the geography and climate conditions are serious, rains, fogs, lightning and typhoon as well as high temperature are common all the year round. Facing these challenges, the power grid enhanced stability control, improved the equipment and strengthen the network structure. In the future, the power grid plans to optimize the disposition of power sources and build digitalized power system.

The Past, Present and Future of Electric Power Systems in China

(1) The revising of criteria of power system planning and operation are absolutely needed to adapt ever-changing conditions and to make the better coordination between security, quality and economy.(2) The main mission of the Ministry of Electric Power is to realize long distance and bulk power transmission from the west to the east and to solve the related technical, economic and organizational problems. To meet the mission, the Ministry of Electric-Power is preparing some planning and operating guides to promote regional interconnections and keeping stable and economic operation of interconnected systems.(?) There are many problems needed to be studied for the new market-oriented structure in power industry.
