PAS-F: Regenerative AC Source + Grid Simulator

The PAS-F Series is a bi-directional AC Source with four quadrant energy feedback function. This product was developed for renewable energy related applications such as electric vehicle & battery testing and can simulate various grid conditions. Our PAS-F Series has a built-in low voltage ride through function (LVRT) which can simulate abnormal grid conditions. Paired with built in STEP and Gradual transitions make the PAS-F a great product for PV Inverter, Bi-Directional, EV, charger and Energy Storage Systems testing.

Key Features of the PAS-F GRID SIMULATOR products:

  • 45kVA-2000kVA

    Output Power
  • 40-70Hz

    Output Frequency
  • Suitable for

    UL1741, IEEE 1547, BDEW, and CEI0-16
  • RS-232/485, GPIB, Ethernet and USB

The PAS-F regenerative grid simulator output is adjustable up to 300VL-N (519VL-L) and 45-65Hz. Creating voltage and frequency disturbances such as steps and drops gives users a powerful instrument for design validation testing of new products. The DSP based controller allows independent phase angle and voltage control for testing against phase unbalance in three phase products.

Constant Power Mode

The Constant Power Mode (CMP) of the PAS-F grid simulator maximizes output power at typical operating voltages. As output voltage is reduced from full scale the available output current automatically increases to as much as 125%. Below 50% of full scale voltage the source delivers full current and some specifications may not be met. Performance degradation such as load regulation and THD at < 1% of full scale voltage could be slightly higher.

Bidirectional Grid Simulation

The Intepro PAS-F Grid Simulator employs the most advanced PWM rectification (active rectification) technology with four-quadrant operation capability. It is able to provide excellent sinusoidal voltage output and achieve very high output voltage and frequency stability. All necessary protection mechanisms are implemented in the electronic circuitry to quickly detect, execute proper actions immediately and active necessary alarms.

User Control

This grid simulator can be controlled by either the touch panel installed on it (the local control) or by the communication channels (eg. RS485) connected to an external computer (the remote control). Either way of control has a user friendly interface which makes controlling and programming this grid simulator much easier than before.

Certification Test

The PAS-F grid simulator offers embedded Low-Voltage-Ride-Through test windows that allow for simple programming used in compliance routines. The PAS-F offers independent phase control to meet requirements such as IEEE1547 where muti-phase inverters must be tested on an individual basis and all phases simultaneously. The PAS-F Grid Simulator is a reference AC source for use in UL1741, IEEE1547, BDEW and CEI0-16 type compliance testing.

The Test Engineers dilemma when testing dispersed energy products such as PV inverters, Energy Storage systems and wind turbines is that the traditional test set up requires a load in parallel with the EUT and AC source. As a result energy from the EUT is burned into the load creating lost energy in the form of heat. The heat often means building infrastructure like HVAC systems must be updated to cool the laboratory or production floor. The PAS-F grid simulator does not require the parallel load and instead full EUT current is sunk into the AC source and 92% of the power is regenerated back to the utility grid. The PAS-F lowers the total cost of ownership and costly infrastructure upgrades.
