1, reactive power optimization, improving power factor

Reactive power optimization transformation is mainly aimed at the technical transformation of insufficient reactive power compensation, unreasonable configuration of reactive power compensation equipment or damage of reactive power compensation equipment. Through reactive power optimization transformation, the loss of distribution system can be reduced, the power supply capacity of distribution system can be improved, the heating of distribution system can be reduced, the service life of distribution system can be prolonged, the reactive power punishment can be reduced or avoided, and the electricity expenditure can be reduced.

2, harmonic control, rectifier balance voltage

Harmonics can cause series resonance and parallel resonance, amplify harmonics, cause dangerous overvoltage or overcurrent, reduce the protection of transmission, transformation and distribution equipment, shorten the service life of accelerating power equipment and electrical equipment, and cause frequent failures and damages (such as computers, medical equipment, high-power important equipment, etc.). ); (2) The power distribution equipment (such as relay protection, comprehensive protection devices, instruments and meters, etc.) is not operating normally, or the switch (circuit breaker) that cannot operate normally is overloaded, resulting in frequent tripping; (3) Damage to reactive power compensation equipment parts, which can't make reactive power compensation, increase line loss and reduce rated capacity of transformer.

3. Line adjustment and load distribution

The technical transformation project of line transformation mainly aims at the problems of potential safety hazard, unreasonable line load, line heating, high electric loss, and inability to get up the compensation power factor. The wire diameter of (1) wire conductor is not proportional to the load. ② The line layout is irregular (the line is messy), or it is close to high temperature or inflammable and explosive places, and there is no reliable and effective safety protection measures. (3) The line is aging, and the insulation grade does not meet the requirements, so it should be improved according to the specific situation.
