Products Manufactured by Westron Are Known in Czech Republic
April 4, 2012

he magazine Atomix (edition of Dukovany NPP, Czech Republic) published an article about the modernization project of radiation monitoring systems at Dukovany NPP, which was successfully completed last year. This article, in particular, reports:
“... A large-scale investment project TPo 3257 “Modernization of radiation monitoring equipment” was implemented. The main supplier for investment corporation CEZ Group was the company I&C Energo and its subcontractors, the company VF, a.s., Cherna Gora (supplier of instrumentation and data processing equipment in CISRK), the company Westron, Kharkov (supplier of equipment for processing and radiation monitoring data presenting, satisfying the highest requirements for safety) and the Russian company Impuls, Pyatigorsk (supplier of components of measuring instruments). The contract with the supplier was signed in late 2009. During 2010, the preparatory work were carried out, the project implementation started in early 2011...“
The system comprises of: multifunctional control and administration device MPKU-150, board for the measurement of ðÍ in the clarifier cone and water turbidity at sample points, built up on high-precision chemical sensors, as well as the next generation dosing pump, ultrasound flow meter, controlling continuous blowdown valve, electrified damper of intermittent blowdown.

Introduction of the control system allowed the implementation of automatic reagents feed regulation and the improvement of the water quality at the clarifier output that was confirmed by laboratory tests, made it possible to perform diagnostics of the processing equipment, to record the procedure of the operational process in the form suitable for assessment.

An article "Preference to the Domestic Equipment" on the modernization of the control system of reserve diesel-electric generators at Rovno NPP was published in "ENERGOATOM of Ukraine" magazine (No.6, November-December 2011).
Implementation of the Clarifier Control System at the TPP Slavyanskaya
January 20, 2012

Westron have completed performing works on design, manufacture, installation, and start-up of the clarifier No.4 control system at the TPP Slavyanskaya. The system has been commissioned.
DDC is based on “Vulcan”/”Vulcan-Ì” hardware and includes sub complex of workstations (SC WKS), which is equipped by input/output subsystem, current and voltage amplifiers, commuting and connection devices.
Software created by National University “Lvivska Polytechnika” secures the work of DDC in the mode of a mathematical model of power units in a power grid and can operate jointly with real excitation systems of different types.
Mathematical model is based on “medium voltage method” which secures steadiness to disturbances and DDC stable operation without time limits.

Using of DDC for electric power stations allows to:
  • Make the analysis and adjustment of excitation systems taking into account operation of other power units of the plant and power grid
  • Make static and dynamic evaluations of processes
  • Test the excitation regulator without its connection to the generator
  • Make analysis of operation of excitation systems under abnormal conditions
  • Estimate the influence of different situations in the power grid for the work of generator’s excitation system
  • Check the generator’s protection triggering
  • Train personnel (in this case DDC is used as a simulator).
