Product information
Product Overview: Static Var Generator (SVG), also known as Static Synchronous Compensator (STATCOM), is a dynamic reactive power compensation device based on high-power inverters. It takes a high-power three-phase voltage type inverter as the core, and its output voltage is connected to the system through reactance, maintaining the same frequency and phase as the system side voltage. The nature of the output power is determined by adjusting the relationship between its output voltage amplitude and the system voltage amplitude. When its amplitude is greater than the system side voltage amplitude, capacitive reactive power is output, and when it is less than the system side voltage amplitude, inductive reactive power is output. This device is currently the third-generation voltage stability and reactive power compensation controller, representing the development direction of flexible current transmission technology. In recent years, dynamic reactive power compensation and harmonic control devices have been increasingly widely used in the power grid and power users to improve voltage stability, improve user power quality, and achieve the goal of energy conservation. SVG is used in transmission networks to improve power system stability, increase system damping, suppress system oscillations, and thus significantly enhance voltage transmission capacity. With the rapid development of cross regional power grid construction in China, the issues of reactive power and dynamic voltage stability in the power system are becoming increasingly prominent. Installing high-voltage and high-capacity SVGs is an effective means. SVG is used in distribution networks (also known as DSTATCOM), which can quickly and effectively compensate for fluctuating loads with dynamic reactive power. It compensates for voltage fluctuations and flicker, load imbalance, power factor, and harmonics, effectively improving power quality while achieving significant energy-saving and consumption reduction benefits. For example, when SVG is used to compensate for loads such as electric arc furnaces and calcium carbide furnaces, the average power consumption can often be reduced by 4% -15%, and the economic benefits are very significant.
