Abstract

The construction of UHV power grid obtain the senior government officials' attention and affirmation, but it is not applause in power industry. There not only have the supporters of the applause, but also the questioned voice of the opponents .The use of 1000kv UHV transmission can improve the transmission power, reduce the line voltage drop and improve the voltage quality. From the simple system power - angle characteristic equation, increasing the possible limit power of the generator is beneficial to improve the stability of the system. 1000kv transmission line over-voltage is more serious than the general high-voltage lines, we can use lightning arrester limit DC device over-voltage level. The use of lower protection level of high-performance arrester can reduce the insulation level of equipment, and then make a few suggestions in the coordination of insulation.
