Product Description
SVG (Scatable Vector Graphics) is the use of turn off of power electronic devices in a self commutation bridge circuit, after the reactors in parallel with the grid, properly adjusting the amplitude and phase bridge circuit of AC side output voltage, or directly control the current of AC side, you can make the circuit absorption or make meet no power current requirements, the realization of dynamic compensation of reactive power of non inductive and capacitive wattless power in a body, has the characteristics of wide instantaneous dynamic compensation to the rapid change of the wattless power. When work is through the IGBT switch device converts the DC voltage to the output voltage with the frequency of the AC side and grid, so it is like a voltage source inverter, but its AC side output is connected is not a passive load, but the grid. Therefore, when considering only the fundamental frequency, SVG can be equivalent as amplitude and phase can be controlled with a grid with the frequency of the alternating voltage source.
Have a lot of advantages of SVG for voltage control, voltage is lower, more dynamic wattless supporting voltage, SVG output wattless current and voltage it doesn't matter, can be regarded as a controllable constant current source; and the system voltage is low, the ability of TCR, MCR type SVC output wattless current decline more.
Graph is more characteristic of voltage and current SVC and SVG compensation. From the figure can be seen, SVG wattless current output capability and system voltage independent, and the compensation capacity of SVC with the system voltage drop and drop quickly.
System structure:
The main circuit of the ROSSVG system to link type H bridge connection type, and the use of redundancy design, meet the operation requirements of "N-1". The main power circuit is divided into the following parts: power unit integrated inverter, Grid Connected Reactors, charging resistor and switch
With the development of electric and electronic technology, resulting in power quality deteriorating caused serious pollution, power grid. According to the actual situation of ROSWELL power and industrial users, power quality monitoring, analysis of electric power and industrial users, and provide power system solution, to provide customers with innovative products that meet their needs, technology, services, and create long-term service and potential value for customers.
ROSWELL was formerly located in Bonn, founded in 1960, is part of the SAXE family. ROSWELL started to automation and control, twentieth Century 80 years in power quality compensation of wattless power industry, is the earliest safety, environmental compensation, depending on the design team to complete, to ensure the safety of the compensation scheme for each customer "tailored" the most reasonable, economy. Analysis of Ross vair dedicated to power quality and solutions, based on the non power compensation and harmonic control, to provide "tailored" is more suitable for the power quality solutions for each customer. Widely used in metallurgy, chemical industry, shipbuilding, building and so on various occasions, for the vast number of users of the production safety, energy conservation, improve power quality to provide a reliable guarantee.
Roswell (Wuxi) company is the German Ross vair Electric Co Ltd strategic partner, enjoy only authorized in China in mainland China and the Asia Pacific region, our goal is to service the Asia Pacific market. China will be the focus of ROSWELL's global growth, at the same time the company will be first-class technology and services to customers, through the first-class product quality, to realize his promise a full range of services and in synchronization with the world level advanced technology.
Technological innovation is one of the important factors of ROSWELL success. In the energy field, we are exploring new solutions, in response to the twenty-first Century global energy challenges.
Our solution is committed to quality and optimize energy use. Our products will create a more efficient, sustainable and competitive new energy model to make contribution, and achieve economic development and environmental protection, harmonious coexistence.
