The invention discloses a principle of an intelligent system tracking and transmitting comprehensive power-saving control system:
the intelligent system tracking and transmitting integrated power-saving control cabinet is a high-tech energy-saving device, which is different from a common power-saving device and a common voltage stabilizer. The method takes a modern control theory as guidance, adopts the most advanced control technology and a special electrical element module to optimize the voltage of a commercial power supply system.
In general, the voltage of a power grid is higher than the rated voltage of the equipment, the power supplied by a power supply to the equipment is P1, and if an intelligent system tracking and transmitting integrated power-saving control cabinet is not installed, P1 is completely consumed on the equipment. The energy really exerted by the equipment is P2, the other part of the energy is P3, the energy is consumed in the form of heat generation and the like, the service life of the equipment is reduced by P1 which is P2+ P3, and the P3 causes electric energy waste. The intelligent system tracking and transmitting integrated power-saving control cabinet can output reference voltage suitable for equipment operation, only P2 is supplied to the equipment, redundant heating energy P3 is reduced, Ps is the power consumption of the power saver, and the total power is as follows: the P1 is P2+ Ps, the saved electric power is P3-Ps, the saved electric power is very small and generally does not exceed 1% of the capacity of the power saving system, the P3 dynamically changes with the voltage of the power grid, and the output power P2 is basically constant. The tracking and transmission integrated power-saving control cabinet can output an optimal matching use power P2 for different types of equipment intelligent systems.
The voltage reduction technique is basically constant only for the load impedance. Where P represents active power, V represents voltage, and Z represents load impedance (including power factor). For such a load, the current also decreases with decreasing voltage, giving the formula p ═ V/Z.
The intelligent system tracking and transmitting comprehensive power-saving control system adopts an energy-saving reactance type stable voltage regulation technology to balance the voltage of a three-phase system, reduces the potential difference of unbalanced three-phase voltage of a power supply system to the minimum, ensures the safe, stable and reliable operation of electric equipment, prolongs the service life of the equipment and reduces the failure rate of the equipment.
The instantaneous output voltage is automatically adjusted, even if the input power grid has large fluctuation, the output voltage is basically kept unchanged, the function is complete, the operation is convenient, the current amplitude limit is realized, the overvoltage protection is realized, the back-rising brake is realized, and the rotating speed tracking smooth soft start is realized.
