IoT-Based Monitoring and Management Power Sub-Station of the University of Mosul

Abstract

Managing power plants usually involves monitoring many data and parameters that occur within minutes, hours, or days. Nowadays, a mount of digital data can be exchanged, analyzed and easily accessed through modern technology called the Internet of Things (IoT). In this paper, an IoT (using Wi-Fi development kit called Photon) is used to remote control and monitor the performance of the University of Mosul power plant. This includes monitoring the Power Factor, supplied voltage and total load current of each sub-station within the university area. The system also applies a safety feature to completely close the power plant in the event of a serious condition such as a fire. ThingSpeak is used in this paper as an IoT analytics platform service which lets the programmers collect, visualize and analyze incoming data streams to the cloud. The collected data is sent to the ThingSpeak by the Photon devices, create instant visualization of live data related to the monitored station, and send the required alerts. The engineers responsible for the station can monitor the progress of the work of the station through any connected device - a computer or a smartphone - from anywhere in the world and even reprogram the system during operation, if necessary.

Cloud-Based Automated Power Factor Correction and Power Monitoring

“…Non-linear household loads were concerned; in addition, the consumer will be provided with information about the load generating low power factor and how to minimize it through IoT. Mohammed et al [19] used a Wi-Fi kit named Photon to control and monitor the Mosul University electricity plant activities remotely. Supervise voltage, devices load current, and valuations power factor were included in this term.…”

“…(2) The majority of schemes deal with industrial loads and employ static capacitance values [15,17,19,21].…”

“…(3) The estimation of capacitance that was added to boost the power factor was not exact in some projects [13,19].…”

“…(5) Adding extra capacitance can cause an inaccurate power factor in some research studies [18,19]. (6) In most endeavours, in order to correct the lagging power factor, solid-state relays are used [11,15,16].…”
