Common use instrumentation center

The common use instrumentation center (hereinafter referred to as Center) was established to ensure high quality experimental researches, tests, checkout and calibration of hardware and software in a scientific direction "Automation and computerization of energy".

The Head of the Center: Candidate of engineering sciences, senior researcher Slynko Volodymyr Mefodiyovych.

The main areas of the Center’s focus are:
- the measurement of electromagnetic parameters (currents, voltage, their harmonics, and symmetrical components) of electrical energy facilities – generators, power transformers and autotransformers, reactors, high-voltage power circuit-breakers etc.;
- the diagnosis of the devices of relay protection and emergency automation of power systems;
- solution of the problems of optimal structure design of electrical measuring and recording apparatus for diagnostic information systems;
- metrological tests of hardware and software to determine the operating parameters of electric power facilities, the measurement of electrical energy parameters and control of their quality;
- execution of synchronous measurements of the electrical parameters in a single format of astronomical time by the signal receivers from GPS.

To address these challenges, a unique scientific equipment from the leading manufacturers such as FLUKE and DOBLE is used in the Center.

To execute the precision metrological measurements and calibration of the devices and equipment, monitor electric energy parameters with high accuracy a three-phase standard - calibrator of electric power FLUKE 6100 is used in the Center, and allows to ensure the accuracy and repeatability of the measurements, and technology of their execution in accordance with certain standards. The calibrator FLUKE 6100 also allows to synthesize the sources of electricity with nonstandard characteristics of the widespread spectrum and range, forming up to 100 different harmonics at a time.

To perform experimental researches and tests of the apparatus of automation and relay protection, the simulator model of power system DOBLE F6150 is used, which allows to design and simulate the power system to a high precision, thereby reproducing the processes coordinated in time, and has the function of onset of generation of test signals using GPS. This device is also used to diagnose and monitor the characteristics of emergency events recorders by dynamic tests through the test signals of sinusoidal form and modeling of transient processes, the creation a computational model of the system, formation of harmonics, DC transient, and oscillations.
Special software allows to monitor the selected parameters of the experiment in a real time, and receive all necessary metrological characteristics in the electronic form on PC after processing measurement results.
