PZGW generator sets enable obtaining electricity from water generators and enable transmission of this energy to the existing power grid in the 22-355 kW power range.

• Nominal grid voltage: 3 x 400VAC@50 Hz
• Nominal power: 22-355 kW
• Output power factor: cosφ = 1
• Efficiency: η> 0.95 (excluding generator efficiency and coupling passive elements)
• Total Harmonic Distortion: THD < 5%
• Equipped with a voltage boosting system in the DC circuit of “boost” type
• Work “on the network” with the possibility of autonomous “island work” (“off-grid”)
• Anti-islanding protection, that is, the possibility of automatic separation of the receiving network in the event of a power outage in the public power grid.
• Short-circuit, over-/undervoltage, temperature, and voltage or phase loss protections; the occurrence of load asymmetry.
• Mounting: in the control cabinet
• Overload capacity: 1,5ln 60s every 10 min
• Degree of protection IP20
• Voltage from the electrical machine side: 3 x 0..500 VAC
• Detachable signaling and control panel with LCD display
• Built-in PLC
• Built-in RS232 / RS485 communication module (Modbus)
• Programmable structure:
  1. switchable control variants (A, B);
  2. speed reference (control panel, analog input, PID controller, motopotentiometer, function block);
  3. start control (control panel, digital input, function block);
  4. Programmable digital inputs: start, direction, operating lock, external fault, fault reset;
  5. programmable digital outputs: readiness, operation, failure, no failure, warning, exceeding the programmed heat sink temperature, reaching the set speed,current limitation, function block);
  6. programmable analog outputs.
• Measurement of working time
• Lockout and diagnostics system
• Keyboard protection with an access code system
• Defined sets of factory parameters
• Climatic working conditions:
  1. ambient temperature from 0°C to +50°C;
  2. humidity from 5% to 95%;
  3. pressure from 860 hPa to 1060 hPa.
