基于ZigBee的分布式能源谐波电流监测系统
摘要:分布式能源发电及并入传统电网的过程中，大量电力电子设备的应用会产生谐波，影响电力系统供能质量，为此设计了一种谐波在线监测系统。采用自行研制的基于罗氏线圈原理的谐波电流传感器，结合A/D及快速傅里叶变换(fast Fourier transform，FFT)算法可准确获取各次谐波电流幅值，然后通过ZigBee无线组网实现多节点谐波电流的实时监控与显示。谐波电流采集模块和ZigBee数据传输模块试验结果验证了该监测系统的可行性，与传统监测系统相比，该系统可实现多点谐波电流的无线监控与显示，适于分布式能源发电系统等应用场合。
Abstract：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.
