| 摘 要： | 在电力系统中,高低压电磁环网运行的弊端很大,各电力系统已经陆续解开了220/110kV电磁环网;但近年来新的500/220kV电磁环网又在不断形成;根据影响线路传输能力的3个因素（线路导线的热稳定电流、稳定传输的有功功率、自然功率）的理论研究,以及实例分析,可得出从安全和经济两方面来看,解开500/220kV电磁环网运行将更好.

| Abstract: | In the power transmission system, there are great disadvantages in the transmission with electromagnetic circuits of high and low voltage. The 220/110 kV electromagnetic circuits have been untied successively,but the new 500/220 kV circuits are forming. Three elements are influential to the transmitting capacity, which are heat-stable electric current, stably-committed active power and natural power. On the basis of the theoretical research of these elements and the analysis of some real cases,the conclusion is reached that the transmission may be safer and more economical when breaking the 500/200 kV circuits. |
