Company Profile
As a national high-tech enterprise, ShangHai YingTong Electric Co., Ltd, since 2009, located in Songjiang District of Shanghai, covering 10,000 m2, is a professional science and technology enterprise engaged in R&D, production, and sales of products of power electronics and power automation technology. The Company focuses on smart power grid, power quality, power automation, power saving, and new energy power generation. On the aspects of energy saving and consumption reduction, improvement of power grid safety and stability, and improvement of power quality, the Company independently develops multiple series products in three fields, i.e. power quality and power safety, power saving, and power automation, which have been applied to the power, industrial, petroleum and other key energy consumption fields.
Our company focus on sales and service of Active Power Filter(APF), Static Var Generator(SVG), 3 phase load balancer, hybrid reactive power compensation cabinet. In addition to the main products, we also provide customized services such as scheme design, product customization, equipment maintenance and other customized services.
Active Power Filter APF
YTPQC-APF Active power filters from Shanghai Yingtong are the ultimate answer to tough power quality problems caused by harmonics, load unbalance and reactivepower demand for all applications by all types of customers. They can be installed in LV networks and in MV networks through the use of a suitable coupling transformer.
Shanghai Yingtong active power filter YTPQC-APF is a perfect and comprehensive solution to the power quality issues of power grid, such as harmonic wave, reactive power and three-phase load unbalance. YTPQC-APF active power filter which is in parallel to power grid can detect the harmonic wave in power grid in time, generate the reverse-phase compensation current through the converter and dynamically filter the harmonic wave in power grid. The operation of YTPQC-APF active power filter is unaffected by multifarious load forms and power grid structures. And it will not produce harmonic oscillation along with the system, thus perfectly realizing harmonic control under diverse loads.
YTPQC-APF active power filter can fully accomplish dynamic reactive compensation, control the capacitor switching and ultimately heighten the power factor of power grid. Meanwhile, YTPQC-APF has the function of controlling the three-phase load current unbalance, thus comprehensively handling various power quality matters in power grid.

Why Choose Us
Our Harmonic detection algorithm of Active Power Filter is based on ADALINE(Adaptive Linear Neuron): The error values of output compensation harmonics and load harmonics are adjusted adaptively to speed up the convergence speed and automatically adapt to different load conditions without any special control parameters setting..
For thyristor rectifier loads, contrast result as follows,
(Yellow: Load Current Red: APF Current(output) Blue: System Current)

APF Features and Benefits
OUTSTANDING PERFORMANCE
* Reactive power compensation: Cos Φ = 1.00.
* Continuous correction – step less control. SVG controls from 0 – rated kVAr as one continuous range.
* Capacitive and Inductive compensation: -1 to +1.
* Full correction in less than 5ms. Suitable for highly dynamic loads where the power factor fluctuates rapidly or in big steps e.g. saw mills, cranes, welders.
* No over compensation or under compensation as experienced with capacitor switching systems.
* Current imbalance correction can correct for load imbalance across all three phases.
* Continuous correction – step less control. SVG controls from 0 – rated kVAr as one continuous range.
* Capacitive and Inductive compensation: -1 to +1.
* Full correction in less than 5ms. Suitable for highly dynamic loads where the power factor fluctuates rapidly or in big steps e.g. saw mills, cranes, welders.
* No over compensation or under compensation as experienced with capacitor switching systems.
* Current imbalance correction can correct for load imbalance across all three phases.
* Excellent filtering result and provides harmonics compensation up to 90%
COMPACT HIGH PERFORMANCE
* Compact High Performance.
* Wall mount or cabinet mount in an ultra-compact design.
* Modular design permits 600A within a single cabinet.
* Can be incorporated into electrical switchboards.
NETWORK FRIENDLY AND HIGHLY STABLE
* Unaffected by harmonic distortion and free from harmonic resonance.
* Unaffected by network voltage drop. Even under reduced network voltage levels full reactive current can be provided to meet working conditions.
* There is no nasty transient voltage spikes caused by the switching of capacitors.
* Presents to the electricity grid as a very high impedance device. Network companies need not worry about the attenuation of ripple injection signals.
