Loss Reduction Control Strategy of on-Load Capacity-Adjusting Transformer Based on Load Forecast

Aiming at the problem that conventional on-load capacity-adjusting transformer adjustment methods are susceptible to load fluctuations, a new on-load capacity-adjusting transformer control strategy based on load forecasting is proposed. Convert the load forecast results into step waves with the same time interval, take the average of the predicted load in this time period as the step value of the step wave in this time period, the step wave signal formed is passed to the capacity adjustment judgment module, and the capacity adjustment is performed according to the judgment result. The simulation results show that this control strategy can effectively avoid the frequent action of the capacity-adjusting switch in a short period of time while realizing energy-saving and loss-reducing of the on-load capacity-adjusting transformer.
