溪洛渡、向家坝水电站纯直流输电方案研究

对金沙江一期工程溪洛渡、向家坝水电站采用纯直流输电方案可能出现的重大技术问题进行了研究。叙述了两个方面的研究内容 :交流系统故障时交直流系统间的相互作用特性 ,重点是受端系统 (华东系统和华中系统 )发生交流故障时的系统暂态稳定性 ,以及送端系统发生交流故障时的暂态稳定性 ;各条直流线路发生故障时的交直流系统相互作用特性 ,重点是受端系统的暂态稳定性和送端系统应采取的控制措施

A Study on Pure DC Transmission for Hydroelectric Power Station

A Study on Key problems possibly arised in Jinsa River phase I project are carried out. The study contains 2 parts :1. the characteristics of AC DC interaction during AC system fault, especially the transient stability of recieving end system(East China and Mid China System) during AC fault and that of the transmitting end during AC fault; 2. The characterics of AC DC interaction during each DC transmission line fault, especially the recieving end system and control measure shoud be adopted at the transmitted end system. This program is one of the major National researh programs with specially aided funds and is also one of the basic researh programs for the strategic programs of "Power Transimssion from west China to east China".
