电力参数综合探测系统信号调理电路研究与设计

电力参数通常使用电流、电压表、功率表、频率表、谐波表、三相不平衡度计、电压波动和闪变仪等传统仪器进行检测.仪器通用性差,测量烦琐,自动化程度低.针对这个问题,开发设计了一套基于虚拟仪器技术的电力参数综合自动探测系统,论文详细介绍了系统硬件电路的关键部分信号调理电路设计,阐述了系统整体框架及硬件系统各功能模块设计方法,并通过仿真验证了系统的准确性.系统可移植性较强,可广泛应用于电力系统电网、飞机电源电力参数等领域的综合探测.

Research and Design on Signal Processing Circuit of Power Parameters Comprehensive Detection System

Current voltmeter, wattmeter, frequency meter, harmonic meter, three-phase unbalance me-ter, voltage fluctuation and flicker instrument, etc are usually used to power parameters monitor. But,they have many disadvantages such as difficulty to apply into other courses, measuring complex, and low automation. Aim to this problem, we design a set of power parameters comprehensive and automatic de-tection system based on virtual instrument. It introduces system key part signal processing circuit of hardware in detail, which includes system total frame and each function module design method of hard-ware system. Through simulation experiment, it verifies system accuracy. System has stronger portabili-ty, can apply into power system network, and plane power, etc comprehensive detection.
