At the end of December 2014, on the basis of the concluded agreement between PJSC DTEK Pavlogradugol and LLC NPP Zheldoravtomatika, construction and installation work was completed on the reconstruction of the electrical centralization of the station. Central processing facility “Pavlogradskaya” with expansion and modernization (replacement of the BMRC system with the MPC system).

When performing work, use both existing electric switch drives and traffic lights, as well as newly installed floor and post equipment. The software and hardware complex PTK MPC “TEMP” TU U 31.6-34017368-001 2011, is made using software and hardware of computer and microprocessor technology. The hardware and control system consists of microprocessor, relay components, cable networks, power supply devices, control and monitoring objects. The microprocessor part includes an automated workstation for the duty officer (AWS DSP1, AWP DSP2), an automated workstation for electromechanics (AWS ShN) and control and monitoring cabinets with PLC. Information communication between the components of the microprocessor part of the system is carried out using standard industrial communication protocols.

The critical elements of the hardware and control system of the MPC “TEMP” ensure compliance with the requirements for reliability and functional safety in accordance with DSTU 4178:2003. The structure of the system provides the possibility of periodic self-testing and timely detection of failures in its operation, as well as the function of archiving events with viewing, both in message log mode and in video frame mode. For the first time, the power supply installation at the centralization post has implemented the functions of fully providing uninterrupted power supply to all EC systems (both stationary and floor-mounted devices). Issuance of information (quality control of input voltage (for 2 feeders), load current for each phase (for 2 feeders), measurement of current strength in each phase of the power supply of the operating circuits of arrows) on the power rack in the SCADA system is carried out via the Ethernet network, and control of the presence of phases via two feeders are directly connected to the PLC through optical isolation devices.

As part of the project, work was also carried out on the installation and connection of a transformer substation of the KTP-630 type. Operating and maintenance personnel were trained.
