Embodiment Construction

[0011] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are the embodiment of the present invention. One, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0012] At present, the power supply of the on-site power station area comes from the 10kV / 6kV transformation of the distribution network, such as figure 1 shown. When the load current passes through links such as power transmission, power transformation, and power distribution, voltage drop and voltage loss will inevitably occur on the impedance o...

Abstract

The invention discloses a power line characteristic-based brand-new area identification technology, and belongs to the field of low-voltage power line carrier communication and control. According to the technology, a carrier chip tracks all zero passage moments at which commands are received from different power areas for a long time in a zero passage time division communication mode of a low-voltage power line carrier communication system produced by Qingdao Ding Xin according to a phase deviation phenomenon of alternating current power on a low-voltage power line, compares a zero-passage moment of own connected alternating current power, and calculates offset between the zero passage moments; and the accumulated offset of commands transmitted by own power area within a day is minimum, so that the carrier chip can judge own power area. The whole technical scheme is implemented completely by carrier chip software without any carrier electric energy meter and any additional peripheral, so that the cost is correspondingly lowered, and the accuracy is stable and reliable.

Description

technical field [0001] The invention relates to the field of low-voltage power line carrier communication and control, in particular to a power station area identification technology, in particular to a brand new station area identification technology based on the characteristics of power lines. Background technique [0002] In recent years, low-voltage power line spread spectrum carrier communication has been widely used in the field of carrier meter reading. However, when the carrier energy meter is installed, it is not possible to know exactly which station area it belongs to and which phase of the transformer it is powered by. The operation brings a lot of inconvenience, so the power station area identification technology is particularly important. [0003] At present, the power station area identification technology mainly adopts the FSK power carrier signal method or the method of combining the pulse current method and the FSK power carrier signal method. The FSK powe...
