| 1 profile of reactive power compensation equipment | | | | 2 Performance Analysis With the continuous |
| From the technical principles of speaking, reactive | | | | development of power on power quality and energy |
| power compensation device is inductive or capacitive | | | | saving have become increasingly demanding, reactive |
| power network components, as in our country Low | | | | power compensation device's position in the |
| Power to overhead lines and basically dominated with | | | | increasingly important, so reactive power |
| inductive load, so the system used by the majority | | | | compensation equipment to improve technical |
| of reactive power compensation device was | | | | performance of a force to be solution. Decades, |
| capacitive, which means that it is Capacitor And the | | | | manufacturers and network-related departments and |
| corresponding composition of ancillary facilities. | | | | which was a lot of work in recent years, reactive |
| Because most concentrated in the distribution | | | | power compensation equipment technical |
| network load, so many years for reactive power | | | | performance has been greatly improved. |
| compensation capacitor is basically installed in the | | | | 2.1 reactive power compensation level of automation |
| power of the medium voltage side and low side, | | | | equipment |
| including the 35kV, 10kV and 0.4kV several voltage | | | | Early reactive power compensation capacitor low |
| levels. Needs from the running, said reactive power | | | | degree of automation can not change operating |
| compensation device consists of capacitors, switching | | | | parameters on the power to judge, need to run the |
| devices, detection and protection devices | | | | personnel during the operation carried out in the |
| composition. | | | | switching operation. When the network changes in |
| The early 20th century, 70s, Xuzhou area requires | | | | frequency when operating in high frequency, |
| users to install the 400V low-voltage compensation | | | | operating personnel will find it hard to increase the |
| device in situ, and Transformer substation Install a | | | | workload. As computer technology, rapid |
| 10kV capacitor compensation device. Then | | | | development of reactive power compensation device |
| low-voltage reactive power compensation devices | | | | is now successfully using computer module device |
| low degree of automation, the majority of capacitors | | | | operation management, relatively high degree of |
| through the air switch by hand and switching, and | | | | automation, network parameters can determine the |
| protection simple and rough, when the capacitor | | | | changes in time, automatically switching reasonable, |
| failure occurs only when the entire group of heat | | | | will not increase the run workload, automation has |
| from the air switch Dual start air switch components | | | | reached the requirements of grid operation. |
| trip, fault removal. The quality of low-voltage | | | | 2.2 the reliability of reactive power compensation |
| capacitor is not enough reliable sealing measures in | | | | equipment |
| poor, often have electrolyte leakage phenomenon. | | | | Early reactive power compensation device can not |
| Was installed in the substation 10kV capacitor bank is | | | | meet the technical performance and reliability of |
| composed of a single capacitor, or connected into | | | | operational requirements, current products have |
| triangles or connected into star, larger, generally used | | | | made many improvements, and improving the |
| for the construction of capacitors room installation; | | | | operation from the product may reflect the problem, |
| capacitor production quality, and insulation materials | | | | the current number of Xuzhou in 2000 put into |
| infusion from the paper and the composition of | | | | operation product is still safe to run, run the life of |
