Main features and advantages of VChRP:

  • Development of VChRP is concentrated in the territory of the Zelenograd Federal Special Economic Zone; the project is approved by the Russian Federation Ministry of Economic Development and Trade; production is situated in the Instrinskiy district of the Moscow region; VChRP passed certification under GOST-R (the Russian state standard) and approved by the expert opinion of the Electric Power Industry Research Institute (OJSC) confirming compliance of functional parameters of the converters to industry requirements and operating conditions at electric power enterprises in Russia
  • VChRP are developed using one-transformer scheme, what results in: simple installation and connection; compact size of the drive; low input harmonics and clean output sinusoid; no input or output filters required; high performance factor, high cos ?; full drive control during operation.
  • Implementation of VChRP is a part of an integrated package of services that includes project development, engineering consulting, commissioning operations and training of personnel.

Implementation of frequency-regulated drives allows:

  • to save up to 50% of electric power by providing the optimum production performance factor;
  • to eliminate hydraulic impacts in the piping system and breakdown of gear wheels and transmission belts;
  • to assure engine hot start in order to eliminate downtime of the equipment when waiting for natural cooling of engine stator coils;
  • to preserve engine control during short-term blackouts;
  • to reduce ageing of costly technological and electric equipment, elevate reliability, extent lifetime, and downsize repair and maintenance expenses, as well as to minimize emergency downtime;
  • to reduce the amount of noise;
  • to improve production quality and reduce losses by adjustment of performance for each specific production process;
  • to increase production automation level and flexibility of computer control;
  • to collect, process and store drive operation data;
  • to implement all types of equipment protection from emergency operating conditions.

Main control functions:

  • both local and remote control is supported
  • control actions can be initiated by 4-20 mA, 0-10 V, 0-5 V signals, from the operator console, using discrete moreless signals
  • control over RS485 interface; open protocols MODBUS, PROFIBUS, Ethernet, etc. are available as an option
  • PID controller for maintenance of desired pressure, temperature, etc.

Main protection functions:

  • frequency converter short-circuit and overload protection
  • unallowable current overload protection (integrally dependent)
  • frequency converter overheat protection
  • input transformer overheat protection
  • internal and external switching overvoltage protection
  • IGBT transistor power cell breakdown protection
  • frequency converter control circuits corruption protection
  • ventilation failure protection
  • unallowable line undervoltage protection
  • unallowable line overvoltage protection
  • supply voltage phase inversion protection
  • reverse rotor rotation protection
  • phase dropout protection
  • unallowable rotation speed increase protection

VChRP has an advanced diagnostics system that allows to locate problems inside the electric drive at functional part level in case of the protection system actuation.

In case of failure in an IGBT power cell, the electric drive is NOT switched off. IGBT power cells have a bypass function. If a certain IGBT power cell fails, e.g., there occurs a fuse blowing, IGBT failure or overheating, this particular IGBT cell goes into bypass mode, and the control system adjusts phase angles in order to restore balance of the voltage triangle. When an IGBT power cell enters bypass mode, the frequency converter automatically boosts output voltage of working power modules in order to maintain the required output parameters.
