Fast Restoration Algorithm for Generatrix Voltage Loss of Distribution Network in the Malfunction State

In the state of the generatrix voltage loss malfunction (big area supply interruption) in distribution network, how to realize the electrical power restoration plays an important part in the reliability and security of increasing the power supply. This paper gives us a new restoration algorithm, combining with network topology analysis and heuristic search. Within the conditions of system electric current and voltage, the algorithm aims both in the load leveling and the least load rejection, which transfers the influenced load to the non-fail power supply point in a maximum extent. We can get the optimal console switch sequence list through confirming the minimum transferred load rejection list and the comprehensive comparison; then restore the power supply for the malfunction state quickly, in order to reduce the outage loss. At last, the case shows the possibility of the restoration power supply for algorithm area in a short time when we face the situation of generatrix voltage loss malfunction (big area supply interruption).
