The Design And Realization Of High Voltage Reactive Power Automotive Compensation System On Pole

In oilfield, feeder line of 6KV often has many branches .The pole high voltage automotive capacitor compensation system controlled by single chip computer is designed for this situation .In the system, we separate the measure position and compensation position and realize the supervision of reactive load in local area. Thus the reactive compensator can be located in the center of the distributed load in the area and make the best user of the compensator's capacity. The distance flowed by the reactive current is efficiently reduced and the active loss of power net Goes down. Two-stage control model is adopted in the optimized control technique of the system. It not only solves the problem of optimized control of the reactive current exchanging among branches, in other words, realizes the auto-tracking to the reactance factor, but also greatly improved the reliability of the system.To design the high voltage line wireless signal acquisition device with self-feed source, we applied electromagnet induction principle and digital communication technique. The device can measure reactive parameters in distribution power net which are generally considered to he difficultly measuredThe paper also introduces the calculating method of the reactive compensation capacity and its optimal location, the design method and realization principle of the series devices, such as the reactive power acquisition device, the reactive power optimized controller and the compensation capacitor operator, is seated in detail Through economic and technical comparison, a realistic hardware scheme of reactive power compensation system is proposed .
