UNIKOMPENZATOR

UNIKOMPENZATOR 400 is active compensator of power factor, in accordance with the requirements of power distribution companies. Maintains the desired power factor by the creation of inductive or capacitive reactive power. Standard control range of power factor cos φ is from 0.95 capacitive to 0.95 inductive (this parameter is configurable for the whole PVP). Active compensator can be supplied even for higher power factor ranges (0.9 capacitive to 0.9 inductive), if requested.

UNIKOMPENZATOR 400 is a transformerless inverter designed for direct connection of a inverter or arbitrary number of parallel ranged inverters on the primary side of the grid transformer with ratio 0.422 kV.

The main advantages of using UNIKOMPENZATOR 400:

• high efficiency 98.0 % is achieved by using the modern, 5th generation IGBT switching elements; by the use of low loss transformer and by eliminating the self-consumption to minimum as by using the modern low loss magnetic circuits with amorphous metals and ferrite powder materials
• parallel cooperation of individual compensators
• compensator with an LC filter is used as a power converter, which through its control secures “zero” share of higher harmonic flows and adjustable power factor (cos φ): from 0.95 capacitive to 0.95 inductive (normal adjustment: cos φ = 1)
• the controlled rectifier allows the aic synchronization to the three phase grid with adjusting to the instantaneous frequency and voltage
• very low harmonic distortion of the current injected into grid(THDi max. 3%)
• compact unit with inbuilt output contactor disconnection to 10ms at the loss of a phase or unpermitted statuses of electrical grid
• inbuilt AC cut-out switch for disconnection of the device
• indication of kVA and produced kVA for chosen time period
• it meets the requirements of transfer system to quality of voltage and current, it meets all security requirements and EMC standards
• design with focus on high reliability and efficiency – life time several times exceeds period of economic return– the life time is also extended because of replacement of electrolytic capacitors for foil capacitors and the use of bearingless fans (magnetic levitation)
• detachable elements on AC side with mechanical lock
• triple check of disconnection and repeated start–up of power plant by independent hardware monitoring system with the control report sent to superior Control System
• possibility to extend the 5 years standard warranty
• excellent communication possibilities for control by superior Control System by RS 485 with communication possibilities over: Profibus DP, Modbus RTU

Options:

• telemetry – remote access to the control system of the power plant
• online visualization with secured Internet access over Ethernet, GSM, or DSL
• aic notice of alarm status and summary report by E-mail, SMS or FTP
• detachable manual graphic control panel
