Purpose of the development: The system is designed to automatically control the operating modes of the compensator reactive power asynchronous generators small hydro and wind plants.

Recommended application field: Small HPP Hydraulic power station, wind farm.

Technical characteristic: The main technical parameters: - The number of degrees of switching capacitor banks 9; - Maximum power level 40 kvar; - Voltage Capacitor 415; - Operating temperature -20 to 60 ° C; - Self resource capacitor banks and switching equipment; - Remote control modes equalizer settings; - Automatic creation of database parameters of the compensator.

Advantages over analogues: The system is implemented on a specialized microprocessor DCRJ-12 Lovato Electric Company with communication port RS-232 and RS-485 (Protocol MODBUS RTU). Availability of communication interface RS-485 allows you to program the equalizer modes and to obtain the central control power plant (WPP) necessary information about the parameters of the generated electric power and self-diagnosis. The control system also incorporates an internal temperature sensor, programmable input external temperature sensor, clock / calendar with the event log, a set of additional advanced functions (over-current measurement of capacitors, harmonic spectrum of current and voltage, the average power for a week, saving the maximum value of the electric power, preservation of harmonic components)

The development stage readiness: Ready for application

Technical and economic effect: Pilot operation 6 jacks on the objects of the state enterprise "Operational and Technical Department" Vodenergoremnaladka "(AMC Crimea, Simferopol). Basic services: - Development of technical specifications for the creation of the equalizer for a particular object; - Development of circuit solutions for a particular object; - Detailed design including the compensator; - Support of production; - Support of commissioning; - Support of the trial operation.

Description of the development:
()
The compensator consists of regulated and unregulated units and connected to the 0.4 kV buses transformer substation. Regulated Power has 9 stages switching capacitor banks. Switching is done using specialized contactors to limit the inrush current. Power Capacitor is selected according to the rated parameters generator. Compensator operates automatically under microprocessor systems. The measuring part can be connected as a voltage 35/10 kW for reactive power at high voltage side of the transformer station, and on the side of 0.4 kV.
