Development of an Industrial IoT Based Monitoring System for Voltage Regulators
Abstract : The increase in electronic loads connected to electrical network became relevant requirements of the quality of supply. Among the equipment used in the power distribution system stands out regulators medium voltage installed over the grid to maintain voltage levels within indifferent operating range of the oscillations. Therefore, the quality of supply has become a priority and the implementation of technologies that allow transforming conventional electrical distribution networks into intelligent ones is strategic for Distribution Operation Centers (COD) to perform remote interaction with the equipment, in this case, with a power regulator. medium voltage. In this context, this article demonstrates an IoT (Internet of Things) solution for monitoring and controlling medium voltage regulators, through the use of LPWA (Low Power Wide Area) networks, integrating this equipment with the concepts of Smart Grid (SG). The complete development of the project is presented, including the study of the communication protocol DNP3 (Distributed Network Protocol 3), responsible for the exchange of information, between the hardware system and the voltage regulator, the communication system being through the Sigfox and GPRS (General Packet Radio Service), transmitting the regulator data to supervision software. Validation of communication hardware and software with the medium voltage regulator, occurred with bench tests in expressive periods and, after installation in the field, the experiment was validated by reading and recording parameters, such as number of maneuvers, voltage and mains current, obtained directly from the voltage regulator.
? The main contribution of this paper is to extend the existing body of literature by providing energy policy-makers, economists, energy experts, and managers with a general overview of the opportunities and challenges of applying IoT in different parts of the entire energy sector.
? There are variety of sensor and actuator devices, communication technologies, and data computing approached, in this section, we explain the existing technologies which enable IoT.
? Different types of sensors exist that are developed for various application purposes.
? The recent developments in digital technologies have provided a driving force to apply smart, IoT based solutions for the existing problems in a smart city context .
? The trends in the vibration frequency spectrum is simulated and observed frequently to know the problems such as unbalance, misalignment, bearing defect, resonance, looseness and electrical problems.
? Typical wear-and-tear, digging, rodent damage, theft, etc., are all examples of problems that can damage wire.
? The deep level of control afforded by IoT allows rapid and more action on those opportunities, which include events like obvious customer needs, nonconforming product, malfunctions in equipment, problems in the distribution network, and more.
? It also limits the problem of lack of proper conditioning and maintenance of the machines.
• The research in proposes a wireless sensor and actuator network to provide an IoT-based automatic intelligent system.
• Whereas, by optimizing the operation of devices and machines in the IoT, the proposed system achieves reduction in their overall energy consumption at a given time.
• Another study proposes an energy management system for smart homes that utilizes BLE for communication among home appliances aiming at decreasing the energy at homes.
• The work proposes a platform by integrating multiple systems, such as air-conditioning, lighting, and energy monitoring to perform building energy optimization.
• Other solutions propose designing co-simulation models for energy systems to integrate the system and minimize synchronization delay error between the subsystems.
? The development of IoT-based monitoring, improved DC Motor control performance is also growing.
? While the authors, have developed IoTbased monitoring systems for the efficiency of solar power plants.
? Automation is a self moving that means operating the system without the human interaction and get the performance compare manual operation.
? This leads to the faster communications, latency, saving time, conserving energy and cost saving, gives efficiency and accuracy, optimum utilization of the energy saves the money.
? The use of PLC to implement industrial automation system, it requires a lot of time for debugging, the cost also very high efficiency is less that is depends on Umbworld.
