Novosibirsk State Technical University (NSTU) has launched a project to develop an electrical monitoring system for local power facilities with small and microgeneration. The implementation of the system will make it possible to measure operating parameters, monitor the permissibility of processes in the electrical network and, if necessary, control electrical equipment.
Ilya Dulov, Associate Professor of the Department of Automated Electric Power Systems at the Faculty of Energy of NSTU-NETI, Candidate of Technical Sciences, said that the interest in developing a system for monitoring the operating modes of power facilities is caused by the massive development of distributed small and microgeneration.
"The massive introduction, operation and development of distributed small and microgeneration in the country has led to the need to create affordable systems and tools for monitoring their operating modes of such power facilities. Such systems are the basis for the functioning of devices for controlling their operating modes and monitoring their current state," the scientist said.
The author of the development was Andrey Kompisenko, a graduate student at the Faculty of Power Engineering The device is a microcontroller with an analog signal conversion system, which implements an algorithm for measuring mode parameters. With its help, it is possible to determine the parameters of the elements of the electrical network, perform a priori control of the acceptability of the operating mode of electric receivers and form control actions on them.
According to Ilya Dulov, the monitoring system will allow monitoring the power, voltage and frequency in the network, as well as the amount of energy that can be exchanged between facilities within the framework of controlled demand. This is especially true for private households and small industrial buildings where local hybrid generation facilities combining renewable energy sources with traditional energy are used.
The system of measuring the parameters of the regime will also allow creating the so-called "controlled demand" for electricity. "We are talking about smart contracts between owners of private facilities' generation sources and end users who can interact with each other in terms of energy transmission and sale," Ilya Dulov emphasized.
Earlier, NSTU-NETI developed a method for multi-stage predictive monitoring of the success of starting an asynchronous motor. The unique method, which has no analogues in Russia and abroad, makes it possible to ensure the reliable operation of local power supply systems with commensurate total generation capacity and large single engines.
