| Abstract: | An algorithm for voltage and reactive power control device based on expert system is proposed. By fully using the historical data, the coefficient of the voltage deviation and reactive power deviation of the transformer and compensating devices are obtained and used to modify the rated coefficient. The difficulty of rectifying strategies for voltage and reactive power control devices is solved with the implementation of the programmable strategy. The scheme proposed has been verified in the practical project and the results show that the new device can self adapt to the voltage variation in a regular region and implement the reasonable balance of reactive power flow to increase the security and economy of power delivery. |
| Keywords: | voltage and reactive power control substation automation expert system |
