An effective algorithm is presented for the working voltage of DGAC using this model. The working voltage is nearly related to the geometric parameters of DGAC, the sensitivity of the circuitry and the number of discharges. Computing results confirm that the working voltage increases with the ratio of the radius of the anode to that of the cathode. The number of discharges follows the similar rule.展开更多

The major pressure faced by the electricity industry has now turned from the contradiction between coal and electricity to electricity quantity. This is undoubtedly a true and new test to electricity enterprises which get used to high growth but are now suffering great losses. The reform of electricity system has already been in great difficulties and now is getting into a more serious situation. In order to help readers improve their knowledge and understanding of the current tough situation faced by the electricity industry and discuss how to alleviate and get through the difficulty resulted from the economic crisis "encountered once every one hundred years" by joint efforts of all parties concerned,a Seminar on Crisis and Countermeasures for Electricity Industry was held on November 20,2008. Here are some extracts from the speeches of four experts.展开更多
