Embodiment Construction

[0035] see figure 1 It can be seen that the online monitoring network of power transformers in smart substations is divided into a three-layer structure. The top layer is the main station 1, which is mainly used for overall monitoring and is generally located in the general monitoring room within the jurisdiction. The second layer is the data communication server 2, which is located in each In the substation, it is used to collect the monitoring data of the transformer 3 in the substation, and transmit the data to the main station 1 through the network. The third layer is each transformer 3 in the substation. There are several monitoring units inside each transformer 3, each The monitoring unit transmits the collected data to the data communication server 2 in the station, and communicates with the data communication server 2 using the IEC61850 communication standard.

[0036] see figure 2 It can be seen that for the transformed smart substation, considering that the various...

Abstract

The invention discloses on-line monitoring networking of a power transformer of an intelligent substation. The on-line monitoring networking synthetically considers all on-line monitoring projects of a current power transformer, namely on-line monitoring of gas dissolved in oil and micro water, on-line monitoring of casing pipes, on-line monitoring of winding fiber temperature detection, on-line monitoring of partial discharging, on-line monitoring of iron core grounding currents, on-line monitoring of infrared temperature detection, on-line monitoring of vibration, on-line monitoring of transformer load capacity and the like. Basic configuration, technical parameters and the like of each monitoring project are comprehensively studied and ruled. According to the on-line monitoring networking of the power transformer of the intelligent substation, on-line monitoring technology of the power transformer of the intelligent substation is studied in detail, and all the monitoring principles and monitoring technology indexes of on-line monitoring units of all current and national transformers are studied in an omnibearing mode. A monitoring unit of the load capacity of the transformer is firstly raised and applied, and detailed study is performed on software functions of an on-line monitoring system. A set of complete and formal technical standards of the on-line monitoring system of the power transformer are set up for the intelligent substation.

Description

technical field [0001] The invention relates to a power system monitoring system, more specifically, to a network for on-line monitoring of substation power transformers. Background technique [0002] At present, there is no online monitoring unit technical parameters, software and hardware configuration, and system functions in the power grid across the country to carry out complete and systematic normative constraints. The transformers in each substation are monitored by the station, and it is impossible to grasp the work of each transformer in the jurisdiction as a whole. Status, released as a work order. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a networking system capable of intelligently monitoring the transformers in each substation within the jurisdiction on-line. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: the online monitoring network...
