Static Var Generator (SVG):
The Static Var Generator, is a reactive power compensation system, used for compensation of normal or dynamic three-phase, balanced or unbalanced loads. The Static Var Generator (SVG) system is composed of a fixed-type Static Var Generator (SVG) module, a door mounted display monitor and a SVG system cabinet. The external CT is used for the detection of load current and extraction of reactive power that needs compensation, based on which, the Static Var Generator (SVG) controller controls the main power circuit to generate reverse reactive current in this way, the load-carrying reactive power is counteracted
Highlights Of Static Var Generator
- Stable reactive power compensation for capacitive, inductive, positive sequence, negative sequence and zero sequence loads
- Rapid dynamic responses, stable parameters & high precision of reactive power compensation
- High efficiency, low thermal loss and advanced ECO mode achieve intellectual energy saving
- Modular design offers a variety of coordination with various compensation capacities
- The system adopts an advanced 3-level structure & consists of digital signal processors (DSP), large programmable controllers & high power electronic devices, which has excellent performance and superior reliability
- Supports remote power on/ off functions via computer monitoring.
Features of Static Var Generator
- Static Var Generator has high reactive power compensation accuracy
- Static Var Generator (SVG) can correct both Leading & Lagging PF
- Fast response to Dynamic load variations
- Complete response time (from reactive power generation to elimination) of SVG is less than 20ms (1 cycle), with instant response time of < 100 micro sec. which enables SVG to improve Power Factor for fast changing dynamic loads
- Static Var Generator capacity increase in pace with load changes
- High adaptability, reliability and stability
- For harmonic filtration ,. the SVG can be complimented with tuned filter banks of 3rd, 5th, 7th & other as per network requirement
- SVG ambient temperature: -10°C to +50°C
- Input voltage range: 308V~480V (For 415-440V Network) 432V~880V (For 480-690V Network), 50/60Hz ±10%
- SVG is not affected by harmonic currents
- The Static Var Generator is completely modular in structure. Each module can work independently, and modules can be paralleled to increase the capacity
- Actual output capacity is the same as rated capacity
- Each standard SVG system cabinet can be connected to up to 7 modules in parallel. As for the non-standard cabinet, the quantity of the modules installed inside could be varied according to final rating required. The Touch screen HMI is used for monitoring and controlling the Static Var Generator module online.
- Active compensation technology avoids harmonic resonance.
