Local Reactive Power Compensation Electric Power Optimization Capacitance Cabinet
Product Overview
The reactive power compensator consists of three basic function modules. Detection module, control operation module and compensation output module.The working principle is to detect the current information of the system by the external CT, and then analyze the current current information, such as PF, S, Q, etc., through the control chip; then the controller gives the compensated driving signal, and finally the inverter circuit composed of the electric electronic inverter circuit emits the compensated current.
The SVG stationary reactive power generator uses disconnected power electronic devices to form a self-switching bridge circuit. After the reactor is connected in parallel on the power grid, the amplitude and phase of the AC side output voltage of the bridge circuit are appropriately adjusted, or the AC side current is directly controlled.Quickly absorb or emit the required reactive power, to achieve the purpose of rapid and dynamic adjustment of reactive power.As an active compensation device, not only can the shock current of the shock load be tracked, but also for the harmonic current.
Functional Characteristics
◆ Rapid response ability
The SVG stationary reactive generator employs a state-of-the-art algorithm that dynamically time for dynamically compensation grid reactive power of 1ms.
◆ Highly Reliable
The SVG static reactive power generator has various protection functions, such as output overcurrent, DC side overvoltage, DC side undervoltage, AC side overvoltage, AC overvoltage, IGBT dead area protection, IGBT protection and I G B T comprehensive protection, to ensure that the equipment reliably exits from operation or protects the system and equipment.
◆ Large Capacity Compensation Capacity
The SVG stationary reactive power generator achieves unlimited cabinet expansion expansion, making the compensation for large-capacity harmonics possible, and greatly reducing the cost.
◆ Simple Operation Method And Structure
The SVG stationary reactive power generator is simple to operate and only runs in parallel with the load into the system without other operations.The internal structure is simple, the converter is a modular structure, easy to install and maintenance, access to the system, normal operation without manual intervention.
