摘要：

The maximum allowable voltage variation is a major and often primary constraint in the planning and design of distribution networks. In South Africa the apportionment of the allowable voltage drop between the MV and LV networks is not standardised and often not managed. The best voltage apportionment depends on network and load characteristics, including distribution transformer tap settings. A model is developed to calculate MV and LV voltage and voltage drop limits based on selected network and load characteristics. Comparing the results of the model with load flow simulations show the model to be suitably accurate for application to feeder calculations.
