Abstract

The invention discloses an encoding method for on-line monitoring state quantity of a transformer device. The on-line monitoring quantity code size is limited to 33 bits and divided into three sections, the first section is 1-13 bits, the second section is 14-25 bits, and the third section is 26-33 bits. The first section is transformer substation codes, and is composed of a model area, a control area, object classes, highest voltage grade and transformer substation sequence codes. The second section is main equipment function location codes, and is composed of capacity classes, capacity sequence codes, function location classes and function location sequence codes. The third section is monitoring quantity codes, the 26-31 bits are monitoring classes and monitoring items, the 32nd bit code represents a serial number of monitoring point locations, and the 33rd bit code represents a phase of monitored equipment. The monitoring quantity codes are mounted together with the monitored equipment conveniently and quickly, an implementation mode is simple, and maintenance is facilitated.

Description

technical field [0001] The invention relates to an encoding method for on-line monitoring state quantities of power transformation equipment, in particular to an encoding method for on-line monitoring state quantities combining power transformation master equipment with the IEC61850 logic node naming specification. Background technique [0002] With the development of the power system towards ultra-high voltage and large capacity, and the continuous improvement of the reliability of power supply in society and life, it is urgent to conduct real-time or regular online monitoring of the operating status of power equipment in order to detect early defects of electrical equipment in time. Prevent accidents and provide data support for further equipment condition maintenance and full life cycle management. [0003] In order to achieve the above goals, provincial and municipal power supply companies in the power system have established online monitoring systems for power transmiss...
