基于ZigBee的分布式能源谐波电流监测系统
Distributed Energy Harmonic Current Monitoring System Based on ZigBee
In the process of distributed energy power generation and integration into the traditional power grid, a large number of applications of power electronic equipment will produce harmonics, affecting the power system power supply quality; therefore this paper designs a harmonic online monitoring system. The amplitude of each harmonic current can be obtained by combining the A/D and FFT (fast Fourier transform) algorithm with the self-developed harmonic current sensor based on Rogowski coil principle. Then, the real-time monitoring and display of multi-node harmonic current are realized through ZigBee wireless network. The test results of harmonic current acquisition module and ZigBee data transmission module verify the feasibility of the monitoring system. Compared with the traditional monitoring system, this system can achieve the wireless monitoring and display of multi-point harmonic current, which is suitable for distributed energy generation system and other applications.
