United electrical dissection of ac branch and bus

United electrical dissection of ac branch and bus had important role in accurately grasping quantitative supply and demand information between sources and flows. This paper analyzed the fundamentals and their detailed rules that should be followed by electrical dissection, and proposed a united electrical dissection method for especial and general situations with ac branches and buses being joined. The method solved the problems how various sources and flows of electric power network transmitted along ac branches and interchanged among ac buses. The works of the paper provided theory and method supports for roundly solving the problem of electrical dissection of electric power network.
