Transformer control device and method based on three-dimensional zone diagram policy
Disclosed is a transformer control device and method based on a three-dimensional zone diagram policy. The method includes: setting transformers, including a transformer A and a transformer B; collecting three-phase voltage data and three-phase current data in a power system; rectifying the collected three-phase voltage data and the three-phase current data; transferring the data to the latches in a time-transfer method; transferring the data to an A/D converter of a processor to convert analog signals to digital signals; constructing a three-dimensional zone diagram in the processor; determining transformer operating conditions according to positions of points formed by voltage, reactive power factor and substation load; and adjusting the transformers. This invention adopts a simple, easy and clear three-parameter control policy including voltage, power factors and substation loads, so as to simplify analysis of transformer operating conditions, realize optimal substation operation, reduce transformer loss, and increase economic benefits.
