400v 150kvar Power Supplies Low Voltage Rack Mounted Three Phase Svg

Short Description:

The static var generator, uses IGBT to control the value and phase of AC voltage of inverter, so as to serve the purpose of reactive and harmonic compensation. Static var generator svg can realize fast compensation for reactive load, and achieve very high compensation precision. Noker static var generator adapts the new technology of 3-level, more reliable and high performance.

SVG static var generator is currently the best solution in reactive power control filed. SVG is faster (within 10ms), its compensation precision is high (power factor over 0.99), the compensation method is flexible (SVG can compensate both inductive reactive power and capacitive reactive power), and SVG also has the function of active filtration of harmonic current.

Features

Three phase svg checks the load current through the external CT and performs computing through the external DSP to analyze the reactive content of the load current. After that, it controls the PWM signal generator based on the settings to send control signals to the internal IGBT. In this way, it generates reactive compensation current to implement dynamic reactive power compensation.

1. It supports 15 compensation modes with any priority, such as harmonic, reactive power, imbalance and hybrid compensation.
2. IGBT and DSP chips are reliable brands.
3. Effectively control the temperature rise of the equipment.
4. Adapt to the harsh natural environment and power grid environment.

5. Three level topology, small size and high efficiency.
6. DSP+FPGA architecture, high speed computing power.
7. Strong algorithm, fast response and accurate compensation.
8. Provide customized services for structure, software, hardware and functions.

Product display

The three phase svg adopts the hardware structure of FPGA, and the components are of high quality. Thermal simulation technology is used for thermal design of the system, and multi-layer PCB circuit board design ensures reliable isolation of high and low voltage, which provides guarantee for system safety.

Application

Where there is a low-voltage transformer installed and next to large electrical equipment should be equipped with reactive power compensation devices svg static var generator(this is the provisions of the national power department), especially those with low power factor industrial mines, enterprises, residential areas must be installed. Large asynchronous motors, transformers, welding machines, punches, lathes, air compressors, presses, cranes, smelting, steel rolling, aluminum rolling, large switches, electric irrigation equipment, electric locomotives, etc. In addition to incandescent lighting in residential areas, air conditioning, refrigerators, etc., are also reactive power consumption objects that can not be ignored. The rural electricity situation is relatively bad, most areas lack of power supply, voltage fluctuation is very large, power factor is especially low, installing compensation equipment is an effective measure to improve the power supply situation and improve the utilization rate of electric energy. Three phase svg must the most ideal reactive power compensation device.
