A method for accessing monitoring information of substation primary master equipment to a control system

Abstract

The invention discloses a method for enabling state monitoring information of transformer station primary main equipment to access to a regulation and control system. The method comprises steps that: the state information of the transformer station primary main equipment is received and is classified into on-line monitoring data, off-line detection data, history state information and family defect information; after pre-processing, the data is sent to a threshold diagnosis module for diagnosis; a diagnosis result of the threshold diagnosis module is sent to an expert diagnosis module; the inputted data is diagnosed through the expert diagnosis module, an operation state of the equipment is diagnosed, and a message formed from the operation state information is inputted through a second bus to a multidimensional information display module; the multidimensional information display module is used for identifying state information of the equipment in the message and carrying out classification and display. The method realizes comprehensive analysis determination on the operation state of the equipment through integration of the on-line data, the off-line data, the history information and family defects, not only diagnosis reliability of the equipment is improved, but also content transmission quantity of the message is reduced, and business processing capacity requirements for the regulation and control system is further reduced.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of electric power system automation, and relates to a method for accessing monitoring information of primary master equipment in a substation to a control system. [0003] 【Background technique】 [0004] The construction of smart grid has gradually risen to the level of national strategy in my country, and has become an important part of national economic development and energy policy, and has also become the development trend of the future power grid. As an important foundation and support for a unified and strong smart grid, substations undertake functions such as changing voltage levels, collecting power flows, distributing electric energy, and adjusting voltages. technology and development direction. [0005] The development of smart grid technology has also brought about profound changes in the operation mode of substations and the dispatching mode of the power grid. The operation has also developed fro...

Problems solved by technology

The action of the secondary protection equipment is often caused by sudden changes in the operating parameters of the power grid, including the action of the protection system caused by a serious fault in the operation of the primary equipment.

[0008] There are two difficulties in accessing the status information of the primary equipment to the control system: 1) The current control system already contains the secondary monitoring information of tens of thousands of equipment in more than a hundred substations, how to add the status information of the primary equipment to the control system 2) At present, the primary primary equipment has the conditions for online monitoring and has accumulated a large amount of operation monitoring data, but these data are limited to low-efficiency applications such as alarms, and there is still a lack of data fusion and automatic diagnostic techniques, resulting in unreliable monitoring results

If a large amount of original status information of primary equipment is directly connected to the control system, it will not only increase the load of equipment monitoring on the control system, affect the reliability of the system, but will not help to accurately judge the operating status of the equipment
