Overview of GASVG Enhanced Static Var Generator Products
1. On the basis of high-power switchable devices, applying power electronics technology, computer technology and modern control technology, through the control of the output voltage phase of the device, the network parameters and network structure of the power system are controlled flexibly and rapidly, and the whole range from induction to capacitance is adjusted continuously and rapidly. To meet the requirements of reactive power and harmonic filtering, so as to suppress voltage fluctuation and enhance system stability.

2. GASVG can dynamically compensate zero-sequence current, reactive current and harmonic current, thereby reducing line losses, increasing active power transmission capacity, suppressing harmonics, improving power quality and so on. It is a new generation of SVG products.


Performance Characteristics of GASVG Enhanced Static Var Generator
    1. Multi-function of one machine: compensating power factor, controlling harmonics and three-phase unbalance at the same time
    2. Flexible installation: cabinet-type design of a variety of installation methods, according to user system conditions
    3. Small volume and large capacity: the maximum capacity of a single cabinet is 400 Kvar, which occupies much less space than the compensation scheme based on traditional capacitance.
    4. Fast response: DSP + FPGA control architecture, real-time tracking, dynamic compensation, fast dynamic response (ms level response)
    5. Two-way precise compensation: Compared with the traditional capacitance compensation scheme, SVG can realize capacitive and inductive two-way compensation, reactive power compensation is continuous compensation, compensation error is less than 1.
    6. Good stability: infinite impedance to the power grid, without affecting the system impedance; and the output waveform is accurate, without affecting other equipment.
    7. High efficiency: low power consumption (less than 2.5% of rated power), actual efficiency > 97.5%.
    8. Real-time and flexible monitoring: computer remote monitoring through communication interface facilitates centralized control and management, standardizes remote monitoring interface, and supports remote switch.
