Advanced Static Var Harmonic Filter Generators High Power Density

Introduction to Modular Power Quality Regulators
Our modular power quality products include: Static Var Generators (SVGs), Advanced SVGs (ASVGs) and Active Power Filters (APFs). They have features such as high power density, enhanced reliability, optimized performance, high utilization and unique designs. For use in different application scenarios, there are three way to install them: drawer style, wall-mounted style and upright style.

Main Features of Modular Power Quality Regulators
Our modular power quality regulators:

• Are compact, with a maximum size of only 0.05m³, have a high power density, and apply to a variety of scenarios. In practice, they are more applicable to places where limited space poses a stringent requirement on the ground they could cover, as well as power distribution upgrading projects.
• Employ the same design concepts as industry-grade products, and therefore, highly adaptable to the environment.
• Furnish the module control layer with a board compartment that reaches a dust-proof rating of IP6X and has withstood the nationally recognized third-party lab testing.
• Apply an interleaving control manner at the output end. This reduces at least 40% of global ripple current.
• Support a dynamic response at ms level, with a global response time less than 2ms. Therefore, they can accurately track how transient current changes in the power grid and prevent over-compensation and under-compensation.
• Employ an industry-leading redundant design based on Insulated Gate Bipolar Transistors (IGBTs). As a result, failure in one line will not affect the proper running of the system.
• Allow devices to detach from the power grid in case of a breakdown, with no port capacitors remain connected to the grid, thus preventing any negative impact on the harmonic oscillator and capacitive reactive power of the grid.
• Support a CT connecting at the power supply side or the load side, which you can adjust according to on-site requirements.
• Have a fast and thorough fault self-diagnosis function, which can be intelligently adjusted based on actual operating conditions and states.
• Make it easier to maintain by using separately removable parts such as bus capacitor and fan.
• Support a smart algorithm, which automatically adjusts the compensation proportion based on real-time changes in reactive current and harmonic current, and also supports flexibly setting a compensation goal, in order to optimize your business objective.
• Support smart sleep in which two parallel systems apply a polling mechanism to allocate an average worktime for each module under a light load condition, thus extending module lifetime.
• Have passed the CE certification and conform to EN 62477-1: 2012+A11-2014+A1-2017 standard;

Each of our products has the following compensation feature:

• An APF supports a wider range of compensation, that is, instantaneous 2nd - 51st harmonic compensation;
• An ASVG supports 2nd - 23rd harmonic compensation. You can set harmonic compensation capacity and reactive compensation capacity globally.
• An SVG supports global, instantaneous compensation for inductive reactive power and capacitive reactive power, and meanwhile, solves the three phase unbalance problem.
