VPFE series of intelligent reactive power compensation harmonic measurement and control terminal products are developed by VSK to meet the needs of the new generation of smart grid construction. With high performance microprocessor as the core, full digital design, modular processing of hardware and software, EMC design, anti-interference ability, stable and reliable operation, simple operation. Reactive compensation control terminal is calculated by measuring the voltage and current of power system, reactive power, power factor, harmonics and other parameters, according to the load condition of capacitors for accurate switching control, and can realize encoding compensating reactive power, reduce the power loss; especially suitable for power system harmonic the source of electrical energy quality automatic control device. The products are widely used in electric power, petroleum, metallurgy, coal, chemical industry, airport, port, city and rural areas such as power grid, the power factor and power users reach the predetermined quality, improve the utilization efficiency of electric power transformer, improve power quality, so as to improve the economic benefit and social benefit.

Main features of equipment
1) according to reactive power requirement and power complex control system to control the switching of capacitor bank, the compensation is fine, and the switching vibration is avoided.
2) light green large screen LCD display, clear and intuitive display, a screen can display a variety of acquisition parameters, overcome the digital tube needs multi screen display shortcomings, greatly improved work efficiency.
3) strong anti-interference ability. VPFE control device adopts the fault tolerant technology, do deep processing of electromagnetic compatibility, close cooperation in the field of hardware and software, to overcome the interference of fuzzy switching control, chaos phenomenon, the measurement and control device in high steady state.
4) cold working environment, working at 2500M high altitude and -30 centigrade environment.
5) fast response time, in the dynamic switching operation, within 100MS response action completed.
6) a variety of control options can be selected to meet the needs of users in different field switching. The utility model is especially suitable for measuring and controlling terminals of power quality and harmonic wave filtering equipment.
7) parameter setting is flexible, undervoltage parameters, input threshold and so on, which can be set according to the user's personal needs.
8) has the communication function, uses the MODBUS agreement or CDT 101 agreement.
9) with background analysis software. It is convenient for users to monitor the running status in real time (software needs paid service)
