MAIN GRID SIMULATOR - VARIABLE DISSIPATIVE OR REGENERATIVE LOAD

NETLOAD: REGENERATIVE SIMULATOR OF

ELECTRICAL POWER SUPPLY AND LOAD

Testing of distributed power generation systems in accordance with

the CEI 0-21, simulating the power grid

and loading and regenerating the energy used for the test.

 

- Simulation of single and three phase networks up to 100 KW

- Simulation at various voltages and frequencies

- Frequencies ranging from 45 to 65 Hz

- Load with cosphi set as desired

- Variable load voltage and power

- Load imbalance

- Simulation of fault and phase failure

- Regeneration in the mains

Network simulator

 

By programming the inverter on the generator side to work in the "three-phase voltage generator" you can adjust the voltage and frequency with which power a generator under test, absorbing the active and reactive power generated by the latter.

phase network

Simulation of single-phase mains with adjustable voltage of 110 V or 230 V ± 30% ± 30% and frequency adjustable 45 ÷ 65 Hz (in order to test systems that are born to be connected to both the 50 Hz to 60 Hz).

three-phase network

Simulation of three-phase network (without neutral) with adjustable voltage of 400 V ± 30% and frequency adjustable 45 ÷ 65 Hz (in order to test systems that are born to be connected to both the 50 Hz and 60 Hz).

Load simulator variable

 

In case you want to test the operation of a generator that has the ability to work

in island (off grid) you program the inverter on the generator side in order to work in the "current generator".

Power factor: Freely configurable from 1 to 0 inductive to 0 capacitive

Voltage: can be set to 110 V ± 30% or 230V ± 30% single-phase or three-phase 400 V ± 30%

Technical Features

 

- Framework of conversion and control from 1 to 100 kW, 400 V three-phase inverter with double (back-to-back configuration) for power management:

 - Interface to the grid through a regenerative inverter that manages the flow dipotenza, both in generation and in absorption by controlling the voltage on your DC bus (560-800 Vdc).

- At the same DC bus is connected to the second inverter (inverter side generatoreda 160 kVA nominal) to be properly programmed in order to perform the various functions required during the tests to be carried out in the laboratory (network simulator, simulator load in island, testing with network faults, etc.).

- Isolation transformer to be installed in the external box (400/400 V, 100 kVA) to electrically isolate the system from the mains.
