Power Grid Simulator / AC Power Grid Simulation System

Overview:

The AC2000 series grid simulator is a high-precision, high-dynamic, and high-standard power supply capable of simulating grid characteristics.  Its four-quadrant operation, energy feedback, and voltage waveform editing functions meet relevant standards and test specifications. Users can change relevant parameters such as voltage, frequency, phase variation, three-phase imbalance, and flicker to simulate the required grid conditions for testing the product under test. The energy feedback function effectively saves energy and reduces operating costs. It is suitable for the research and development, quality verification, and production stages of new energy power generation equipment.

Features:

Single-phase or three-phase AC output is available.

 Suitable for testing applications related to PV inverters, smart grids, and EV products

Outputs a synchronized TTL signal corresponding to the output voltage changes.

LIST, STEP, and PULSE modes are used for testing power line disturbance (PLD) simulation.

The voltage waveform can be set with on/off angles from 0 to 360 degrees.

Voltage sag and transient simulation (compliant with LVRT low voltage ride-through testing).

The parameter measurement function includes the hamonic components of the current ateach order.

Synthesis of distorted waveforms from harmonics and interharmonics.
