Abstract

With the rapid construction of a new power system with new energy as the main body, aiming at the problems of high voltage fluctuation intensity and randomness caused by new energy access to the grid, this paper proposes an electric energy measurement method for new energy access by optimizing hardware and software based on high-precision analog signal sampling and measurement algorithm design. The hardware scheme of the measurement module is constructed by using the optimal design of zero-flux current transformer, sampling resistor and high precision ADC chip. In order to improve the synchronization of current and voltage signals and the accuracy of power measurement, a strategy of compensating the phase deviation of current and voltage is proposed. Finally, different experimental conditions are set to verify the effectiveness of the proposed method. The results show that the proposed method achieves high measurement accuracy, which is better than the technical requirement of 0.2S of active power accuracy.
