Wide-area network state monitoring system based on lora communication

Abstract

To meet the requirements of long range, small amount of data transmission, better data correctness and less delay, a wide-Area Network State Monitoring System approach based on LoRa communication is discussed in our Project. The objective is to study and test the performance of Two communication techniques used in wide area monitoring system, a single input single output (SISO) system and a multiple input multiple output system (MIMO) in terms of Bit Error Rate (BER) with varying the signal to noise Ratio (SNR). In addition, we study the Wide Area Monitoring system based on LoRa communication. The IEEE 14-bus power system with Phasor Measurement Units (PMUs) placed at selected buses is considered. The simulation results demonstrate that the MIMO system overtake the SISO system for better Bit Error Rate. Furthermore, the value of the reporting rate has been varied for both systems in MATLAB to see the effect on the data correctness and the results show that the Bit Error Rate value decreases with the increase of reporting rate. Finally, we dealt with a modified LoRa MATLAB code emulator to investigate the data error and delay. The results show that LoRa Technology has better performance in terms of delay and error.
