Problems solved by technology

At present, traditional statistical methods are used to remove data redundancy using fixed coding tables, but any coding rule is difficult to apply to many different scenarios
[0005] Moreover, although there are some data redundancy processing methods, these methods are general methods
There is no mention of a redundancy solution for the three-phase load data in the distribution area

Embodiment Construction

[0034] A three-phase load data transmission method of distribution station area based on dynamic cloud coding, which is used on the three-phase load cloud of distribution station area, and transmits the original three-phase load data of distribution station area from the acquisition unit to the service unit, and according to The corresponding data need to be transferred from the service unit to the acquisition unit.

[0035] The three-phase load cloud of the distribution station area refers to the physical equipment used to collect, detect and analyze the three-phase load status of the distribution station area of ​​the power grid to assist in the completion of three-phase load imbalance control, and the physical equipment running on the physical equipment An umbrella term for the software, and the communications network that connects these nodes. The collection unit refers to the physical equipment deployed on the power consumption side of the user to collect the original dat...

Abstract

The invention relates to a power distribution area three-phase load data transmission method based on dynamic cloud coding. According to the method,encoding is performed according to data such as voltage, current, phase, fault signal, network address and / or physical address in a power supply network; a dynamic coding table is set in a power distribution area three-phase load data transmission process; and the time interval of the dynamic coding table is optimized and updated according to the characteristics of a power distribution area in the power supply network, and the transmission efficiency of power distribution area three-phase load data improved.

Description

technical field [0001] The invention belongs to the field of power supply network transmission, in particular to the field of power supply network data processing. Background technique [0002] In the low-voltage three-phase four-wire power supply system for urban residents and rural power grids, since most users use single-phase loads or mixed single-phase and three-phase loads, the user loads and power consumption time are different, and this unbalanced power consumption situation is infinite. The regularity cannot be predicted in advance, so the unbalanced load among the three phases in the power grid exists objectively. Unbalanced three-phase load will have adverse effects on distribution network power supply security, power supply quality, increase line loss and economic operation, and is one of the main manifestations of the weak links in distribution network operation. In order to improve the quality of power supply and ensure the safe operation of power supply equip...
