Product details
First, TFC dynamic reactive power compensation and active filtering intelligent system
With the rapid development of modern science and technology, a large number of power electronic nonlinear load equipment is used in the power grid, bringing a large number of rapidly changing harmonics to our power grid, which seriously interferes with the normal operation of our power grid, causing frequent failures of power equipment, and even burning the phenomenon of power transmission and transformation equipment, and the reactive power compensation device of the product, and filter equipment can no longer meet the current demand for power quality.
Shenzhen China Resources Technology Co., Ltd., specializing in dynamic intelligent reactive power compensation, harmonic control has lasted for more than ten years, and has accumulated rich experience in dynamic reactive power compensation and active filtering. The application of thyristor intelligent module technology combined with reactance, capacitor bank to do intelligent dynamic filtering reactive power compensation, and then with dynamic active filtering device, effectively suppress or control the 3-50th harmonic generation in the power grid.
Second, the basic principle of dynamic reactive power compensation filter device:
mainly control terminal, thyristor intercrystallium module, capacitor combination, reactor and other components, the controller to load the real-time reactive power, harmonic current, harmonic voltage parameters as the switching physical quantity, the application of advanced harmonic algorithm, within 20ms to complete signal data acquisition, calculation, and control output, to achieve real-time dynamic tracking switching, Fast reactive power compensation and filtering.
Third, the basic principle of active intelligent filtering:
Active power filtering is through a special current transformer, real-time rapid detection of load current, voltage, harmonics and other data, through the control device CPU system analysis and processing of harmonic composition, by the control system internal GBT device to control the inverter to produce a load harmonic current equal to the magnitude, opposite direction of the current injected into the load grid, correction and compensation of the harmonics generated by the load, to achieve compensation and filtering functions.
