Abstract:
Because of time urgent before putting into operation and different place line protection equipment located, joint debugging for extra high voltage (EHV) transmission line is often not perfect although EHV transmission line is very important for modern grid. In joint debugging process, we tend to adopt static method to do fault simulation, that apply analogue to the device. To overcome the shortages of static fault simulation commonly used, which cannot accurately simulate fault characteristics in runtime, a synchronous joint debugging device is designed based on based on the analysis of the joint debugging process for line longitudinal protection. The device is a lightweight and low cost embedded system with the functions of communication and phase shift, and can offer analog signals to protection devices on both ends of the line. Based on the functions and characteristics of the synchronous joint debugging device, the joint debugging process with this device of optical fiber differential protection is analyzed. The functions of this synchronize testing device can meet the requirements, turning static to dynamic joint debugging.
