GSM Based Automatic Substation Load Shedding
S. Pretpal Singh
Automatic substation load shedding (ASLS), Global positioning system (GPS), and Global system for mobile (GSM).
Aim of this paper is designed to control substation load shedding and sharing using a programmable switching control automatically. In this paper this is demonstrated using a microcontroller. The development of this application requires the configuration of the program through GSM module. In substation, there are many tasks like certain loads need to be switched on/off in specific time intervals. In this, the loads can be operated in three modes: Set mode, Auto mode and Manual mode. In set mode, through timers, the operation is based on input time set by the user where as in auto mode it works on default time settings and finally in manual mode it functions while respective loads are operated depending on the load necessity using GSM. All the modes and status of loads are displayed on LCD. Finally GSM modem which sending SMS to the control system can select the mode and timing remotely.
