Modular and Scalable Design

HGS 시리즈는 고성능 및 안정적인 전원 공급을 위해 DMPS (Distal Matrix Parallel System) 방식을 적용하였으며, 이는 고속 광섬유 통신방식으로 최소 300kVA 부터 1MVA 단위로 병렬연결하여10MVA까지 용량 확장이 가능합니다.

특히, HGS 모델은 고장 발생 시 시스템이 중단되지 않도록 redundancy 기능을 갖추고 있습니다. 이는 master 모듈과 다른 slave 모듈이 고장나더라도 시스템이 지속적으로 운전이 가능하여 신뢰성과 안정성을 높여 시스템 down-time을 최소화할 수 있습니다.

4-Quadrant control

4-Quadrant 제어를 통해 PV 인버터, V2G, 전기차 충전기, EVSE, 배터리, UPS 및 AC/DC 전원 공급 장치를 테스트할 수 있습니다. HGS 시리즈는 기본으로 Load 옵션이 내장되어 있으며, 프로그래밍 가능한 위상 제어를 통해 모든 사분면에서 작동할 수 있습니다. 이는 Inductive 부하 및 capacitive 부하를 시뮬레이션 할 수 있어서 완전한 AC 전원 부하를 시험할 수 있습니다.

High Dynamics

The output voltage slew rate of power supply is up to 1V/us, which can simulate the 1ms continuous interruption of the grid.

Harmonics / Inter-harmonics

The 49 harmonics can be superimpose simultaneously, andthe total harmonic content can be set up to 40%

The power supply has two harmonic injection mode, the three-phase independent injection and the three-phase linkage injection, allowing the superimposition of 2-50th of harmonics with 50Hz or 60Hz basic frequency, or allowing the superimposition of 1Hz-3000Hz inter-harmonics to form the distorted waveform of output voltage.

Independent setting of threes phase

Simulate normal and abnormal characteristics of various power grids

The three-phase output of the power supply can be set independently, which can simulate the normal and abnormal characteristics of threes-phase balance or unbalance of various power grids. It can be set by individual or multiple programmable output on voltage, phase etc. of both single-phase and multi-phase.

Voltage ride through

Typical rise / fall time within 1ms

The single-phase, two-phase and three-phase H/LVRT tests can be performed for the power supply. The trigger phase angles of the ride through points can be set for the power supply to meet the requirements of tests under various standards. The minimum setting voltage of power supply is less than 5V, and the rise/fall time is 1ms. Phase A, B and C can be changed at the same time for low voltage ride through, phase B and C can be switched for low voltage ride through, so as to meet the tests of VDE-AR-N 4105 regulations.

Flicker Simulation

Levels 1~10 can be called directly

The power supply supports the setting of flicker levels : the flicker trend chart can be previewed, and the pst can be visualized. The flicker characteristics of the power grid can easily simulated to test flicker adaptability of the test object.

MV Grid Simulation Source

In 2020, ActionPower launched the first generation HGS grid simulator, aiming to simulate the various characteristic of grid on-site, specifically for 10kV/35kV voltage level grid accreditation for field power plant. In 2022, ActionPower launched the second generation HGS grid simulator product, with stronger environmental adaptability, 10kV full power output and other characteristics, and launched series products according to the power station. It mainly carries out grid adaptability tests and fault ride through tests for green energy power stations connected to 35kV/10kV grid. The tests include voltage adaptability test, frequency adaptability test, three-phase voltage unbalance adaptability test, flicker adaptability test, harmonic/inter-harmonic adaptability test, high/low voltage fault ride through test, etc. The equipment is of container structure, it meets the requirements of domestic highway transportation and it can be arranged at various power stations for filed tests. Through the specific design of the heat dissipation air tube, rainwater and sandstones can be prevented from entering the equipments, so that the equipment can still operate normally in harsh environments such as sandstorm, rain and snow. The HGS MV grid simulator still has parallel function, and the maximum capacity can reach 15MW.
