摘要 识别人体触电特征是电网安全防御、用电安全保护、开发新型漏电保护装置等的重要前提。基于生物电阻抗理论,研究人体阻抗α频散特性和人体触电阻抗参数求取方法。利用低压配电网谐波电压,提出一种考虑人体阻抗及其频率散射特性的人体触电特征识别方法。基于PSCAD/EMTDC、MATLAB的仿真实验表明,该方法简单、可行,对于解决当前剩余电流保护普遍存在的死区问题和开发基于人体触电特征的新型漏电保护装置有一定参考价值。 Identification for the characteristics of human body electric shock is an indispensable prerequisite for the security and defense of power grid, the security protection of power utilization, and the development of novel leakage protection de -vices.Based on the theory of electrical bioimpedance (EBI), the method for the frequency scattering characteristics of humanbody and the impedance parameters of human body electric shock are studied .Using the harmonic voltage commonly existingin low -voltage distribution network, the identification method for the characteristics of human body electric shock is proposedconsidering human body impedance and its frequency scattering characteristics .The proposed method is verified to be simple,feasible and fast by the simulation results with PSCAD /EMTDC and MATLAB, which is of reference significance for eliminatingthe dead -zone of the residual current protective devices and the design of novel leakage protection devices based on thecharacteristics of human body electric shock.
