Power supply system simulators

Power supply system simulators

Providing ground testing, conducting autonomous tests, preliminary tests, comprehensive, as well as acceptance tests of power supply systems used both in ground equipment and in aircraft.
Описание
The functionality of the system consists of several basic subsystems:

-Subsystem for simulation of solar panels

-Subsystem for simulating batteries

-Subsystem for issuing control commands and receiving telemetry information

-Control device

Scope



Reproduction of volt-ampere characteristics (VAC) of a solar battery (by individual points, or by a given formula).


Operation in the following modes: maximum power, zero power, transition between the I – V characteristic with a high Uxx value to the I – V characteristic with a low Uxx value.


Hardware and software monitoring and diagnostics of emergency states of electronic components.


Simulation of battery operation: main power channel (charge / discharge), auxiliary power channels (load / output voltage).


Simulation of temperature and voltage sensors.


Support for the MCO (MKI) interface.


Possibility of implementing a system of channel-by-channel balancing of a composite battery using a separate power source for each balanced channel.


Specialized software based on Informtest CAT allows you to fully automate the process of checking the power supply system, exchange information, store, process results, and also allows you to interact with power supplies manufactured by Sorensen, Ametek Power Solutions.

Imitation:

  • Onboard solar battery works
  • Battery work
  • Works tire loads
  • Battery Signals
  • Controller signals Control equipment signals
