The Study On Economical Operation Of Transformer

The energy loss of transformers is great in proportion to all of energy loss in power system, and thereby implementing transformer's economic operation play an important role in achieving economic operation of power system. In the premise of load forecast results of power system, the paper carries out research on optimizing dispatch for transformer's operation. During the course of loss calculation of transformers, the paper imports power-flow calculation and puts forward a general loss calculation scheme under vary operation manner, and creates a mathematics model of optimizing dispatch scheme for transformer's economic operation, and brings forward applying dynamic programming in solution to the problem, and finally presents detail calculation courses。The calculation result of power system composed of two three-coil transforms is satisfying, which proves it available to solve the problems on base of dynamic programming method.
