SIMPLIFIED BUS VOLTAGE ESTIMATION METHOD FOR CHANGES IN SENDING END VOLTAGE AT RADIAL NETWORK AND ESTIMATION PROGRAM

摘要

The present invention relates to a method and a program for calculating a bus voltage. The bus voltage calculating method and the bus voltage calculating program: have simple calculating processes since repetitive calculating processes of a nonlinear equation such as a Newton-Raphson method or a Gauss-Seidel method are not necessary by calculating a bus voltage changed only by the voltage size information of the system when a transmission voltage of the system changes; have no concern about the divergence of the value of the equation; and reduce expenses of a meter installed in the power distribution system.
