Product Overview

The JL-HSVG series high-voltage static var generator is an IGBT-based dynamic reactive power compensation device. Connected in parallel to the power grid via a bridge converter circuit, it regulates output voltage or current to achieve dynamic reactive power compensation. Its core functions include improving power factor, suppressing harmonics, balancing three-phase grids, stabilizing voltage, and eliminating reactive power surges. It is designed to address power quality issues in modern grids caused by renewable energy integration and non-linear loads. Featuring a modular design, the product offers advantages such as rapid dynamic response, strong harmonic suppression capabilities, and flexible operating modes, representing a state-of-the-art solution for reactive power compensation.

Performance Features

①　Rapid dynamic response: Response time ≤ 5ms; tracks load changes in real-time.

②　Strong harmonic suppression: Output current THD ≤ 3% at rated power.

③　Flexible operating modes: Supports six modes, including constant reactive power, constant power factor, and constant voltage; target valuesare adjustable in real-time.

④　Modular design: Power units are connected in a cascaded (series) configuration; easy maintenance and capacity expansion via parallel connection.

⑤　Comprehensive protection: Includes protection against overvoltage, undervoltage, overcurrent, and overheating; supports fault waveform recording.

⑥　High efficiency: Efficiency ≥ 99% under rated conditions; low heat generation and low operating costs.

⑦　Easy installation: Phase sequence independence allows for rapid grid connection; compact footprint.

Technical Parameters

Operating Environment

①　Environmental Conditions:

l Temperature: Operating temperature -20°C to +40°C, daily temperature variation ≤25K; storage temperature -30°C to +70°C.

l Humidity: Monthly average relative humidity ≤90% (at 25°C, non-condensing).
