Abstract

Reliability and accuracy of electric energy metering are the basis to guarantee fairness and justice of electric power market. In China, there are high power users equipped with self-supplied power supply, and the users generally adopt the operation mode of double-bus loop to ensure safety. However, when the power generation changes within a certain range of the load consumption, two metering points of double bus will have a situation of reverse power flow. In the conventional trading mode, the positive and negative electric energy of the metering point cannot accurately correspond to the electricity price of difference in electricity price between the on-grid price and the off-grid price. This paper analyses the electric charge transaction of the metering point under the condition of double-bus loop operation, and designs a calculation method of electric charge based on digital sampling. Through experimental verification and engineering application, it is proved that the calculation method of electric charge based on digital sampling can effectively solve the problem of inaccurate calculation of electric charge, and has certain engineering value.
