Embodiment Construction

[0029] Attached figure 1 Yes 1 is a wiring diagram of the function module of a stepless active power balance and reactive power compensation voltage adjustment method for low-voltage station area.

[0030] Attached figure 1 Among them, the outlet device is installed at the low-voltage outlet of the transformer, and is mainly responsible for the balance of the three-phase active load of the transformer, reactive power compensation and filtering, etc. The communication with the background data processing system is realized through a public remote communication network or a dedicated communication network, and the branch device Communication is realized by power line power frequency communication, carrier communication or moment-distance wireless communication.

[0031] The installation position of the branch device is generally from the low voltage outlet of the transformer to the center of gravity of the user or load, usually tens to hundreds of meters. It is mainly responsible for...

Abstract

A stepless active power balance and reactive power optimization voltage regulation treatment method of a low-voltage transformer area is characterized in that: an exit end power quality treatment device is installed at the low voltage exit end of a transformer, and a branch power quality treatment device is installed at the front of the load of each branch. The user voltage is stabilized, and the branch line loss is reduced.

Description

Technical field [0001] The present invention is the field of electric energy quality control in low -voltage Taiwan areas, especially involving a low -voltage Taiwan area without stepless contribution and balance, unsuccessful compensation voltage adjustment method. Background technique [0002] The current low -voltage platform area mainly refers to 10KV / 400V power supply. The basic wiring method: high voltage is △ connection method, low voltage is Y type, and its power quality is mainly three indicators: one is power supply reliability, the other is the voltage pass rate.One is the voltage harmonic distortion.Power supply reliability describes the ratio of the total time of power supply. It is determined by the power transmission department and has nothing to do with the load status of the Taiwan area. Therefore, for the low -voltage Taiwan area, there are mainly voltage pass rate and voltage harmonic distortion.The power supply unit only evaluates the voltage pass rate of the ...
