Laboratory of Measurement Techniques (MT)

Planned research project programme for the period 2015-2020

1. Physical model construction of three-phase electro-energy system

 

        In the framework of the project, laboratory model of three-phase electro-energy system will be constructed. The model will include programmable low voltage source of internal impedance, frequency and voltage, a three-phase power line, receivers, RLC load programmable with the nature of the work and drive system (machine, induction DC generator, the brake, the energy storage) programmable characteristics of the load torque. The main purpose of construction the model is to verify the methods for measuring the impedance of the electro-energy system harmonics. In addition, the model will be used to study the impact of load on the electro-energy networks of surrogate parameters and to study the metrological characteristics of devices to measure electro-energy quality and system diagnostics.

 

The specific scope of research using the new model:

  • verification methods to measure the harmonic impedance of  electro-energy system;
  • assessment of the impact of load converter on the shape characteristics of  impedance power system;  
  • assessment of the impact of temporal changes of nonlinear loads on voltage distortion at different points in the system;
  • evaluation of the propagation system disorders in electro-energy.

 

2. The position of the measuring apparatus and control for medium voltage systems

In the framework of the project test rig will be constructed. Test rig consists of a dedicated system of medium voltage (MV), in which it will be possible to apply measuring equipment such as medium-voltage converters for low executive and broadcasting equipment like modern circuit breakers and protection (safety) relays. The position will consist of a measuring field for the test and reference transducer such as broadband resistive dividers and inductive transformers.

 

The detailed scope of research using built model:

  • prototype test voltage converter with auto dynamics;
  • determination of frequency characteristics of inductive transducers and transmitters of different design (including the services to external companies);
  • research test equipment operating by standard IEC-61850 (including the verification of compliance with the above mentioned standard of commercial products);
  • research and development of methods for non-contact voltage measurement.

 

 

3. Building a system for recording and analyses of synchrophasors from many points of the national electro-energy system


Within the framework of the project, a focal point system will be created for the registration and analysis of synchrophasors from the national electro-energy system with data storage. As well as, software will be run for storing data received in real time from multiple measurement points, and software to evaluate electricity system stability in real-time and prediction control system.  

 

The detailed scope of research using built model:

 

  • launching an extensive fiber-optic measurement system of synchrophasors;
  • launching the data storage center;
  • development and testing of algorithms to analyze the direction and route of propagation of the disturbances in the national energy system;
  • development and testing algorithms for assessing and providing the electro-energy system instability (rocking, power deficits, etc.) in real time;
  • development and testing of algorithms, in which, task will be responded to the expected instability and real-time control devices stabilizing the system.
