Exploration of Electric Load Calculation Method and Power Distribution System Consumption Reduction

The problems of light load and low efficiency operation of transformer were analyzed. The limitations of calculation load by use of demand factor method and utilization factor method were pointed out. The results show the production process should be taken into consideration in power load calculation. We present a new load calculation method which could exactly represent maximum power load and average power load in a typical production cycle and output load curves. A new method of transformer capacity selection and load distribution, aiming at energy saving and loss decreasing, was provided. And the economical terminal power distribution mode was discussed based on the aforementioned method.
