Embodiment 1

[0060] Embodiment 1: A multi-dimensional correlation early warning method for key equipment in a converter station

[0061] Such as figure 1 As shown, the present invention provides a multi-dimensional association early warning method for key equipment in a converter station, including the following steps:

[0062] Step 1. Obtain the quantity and state quantity historical monitoring data of all key equipment in the converter station, and obtain the attribute relationship, position relationship and logical relationship between each key equipment in the converter station. The key equipment includes converter transformers, converter valves and filters.

[0063] It can be understood that the device attribute relationship refers to the properties of the device itself, including specifications, models, technical parameters, and the like. For example, the attributes of converter transformers of the same model and the same technical parameters produced by the same manufacturer are t...

Abstract

The invention discloses a multi-dimensional association early warning method and system for key equipment of a converter station. The method comprises the steps of obtaining state quantity monitoringdata of all key devices in a converter station; determining a weight relationship of each key device according to a relationship among attributes, logics and positions of the devices; obtaining the incidence relation between the state quantities with the weights of all key devices in the converter station; and determining an early warning result according to the association relationship. Accordingto the invention, the problems that only one key device or one type of key device can be subjected to independent early warning when early warning is carried out on the overall operation state of theconverter station in the related technology, and the relationship among different types of devices, devices at different positions and key devices with different logic relationships cannot be comprehensively considered are solved; therefore, the technical problem that comprehensive and multi-dimensional monitoring cannot be carried out on the converter station is solved.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of electric power equipment, and in particular relates to a multi-dimensional correlation early warning method for key equipment of a converter station. Background technique [0002] The converter station is an important node of the High Voltage Direct Current (HVDC) system, and it mainly undertakes the important function of AC-DC conversion. There are many equipments in the converter station, in addition to including converters, converter transformers, AC and DC filters, reactive power compensation equipment, smoothing reactors and so on. It also includes auxiliary detection systems, station transformers, inspection robots and other auxiliary equipment. The safe and stable operation of the converter station is very important to the HVDC power transmission system. However, due to the large number of equipment in the station and the complex electromagnetic environment, how to comprehens...
