Serial transmission apparatus and transmission method of electric energy system

Abstract

The invention relate to a serial transmission apparatus and transmission method of an electric energy system. The apparatus comprises a transformer substation ammeter (1) installed in a transformer substation; a 458 signal output port of the transformer substation ammeter (1) is connected with a 485 / 232 serial conversion device (2); a 232 signal output port of the 485 / 232 serial conversion device (2) is connected to an MOXA communication server (4) by a communication serial channel (3); and an output port of the MOXA communication server (4) is communicated to an electric energy system server (5) by a network. The method comprises the following steps: step one, obtaining a 485 signal of the ammeter in the transformer substation; step two, converting the obtained 485 signal into a 232 serial signal; step three, converting the obtained 232 serial signal into a network message; and step four, sending the network message obtained by conversion in the step three to a remote server by a network to carry out receiving and decoding. According to the invention, with the apparatus and the method, the hardware investment is low.

Description

technical field [0001] The invention relates to a transmission device, that is, a transmission method, in particular to an electric energy system serial port transmission device and a transmission method applied to a power system, and belongs to the technical field of power equipment. Background technique [0002] With the construction of the power transmission pipeline network, the number of substations has increased dramatically. Taking Jiangyin Power Supply Company as an example, there are nearly 150 existing plants and stations, of which there are nearly 50 user substations under the jurisdiction. The data signals of the ammeters of each substation need to be connected In the power-input energy system, there are more than 20 electric meter data signals in conventional bureau-owned substations, which are transmitted using dedicated data servers and dispatching data network equipment.

[0002] With the construction of the power transmission pipeline network, the number of substations has increased dramatically. Taking Jiangyin Power Supply Company as an example, there are nearly 150 existing plants and stations, of which there are nearly 50 user substations under the jurisdiction. The data signals of the ammeters of each substation need to be connected In the power-input energy system, there are more than 20 electric meter data signals in conventional bureau-owned substations, which are transmitted using dedicated data servers and dispatching data network equipment. Since user transformers and power plants are not equipped with dispatching data network equipment, the amount of electricity data collected is generally one to two. If the standard transmission channel is used, dispatching data network equipment and optical fiber transmission channel shall be installed in the user substation and the power plant, or GPRS mobile data public network wireless transmission shall be adopted. It is necessary to install special secondary security equipment for the power system to ensure data security. The communication hardware equipment of the two requires a large investment and high maintenance costs
