Abstract

The invention relates to a direct-current transmission converter valve cooling water quality online monitoring system and method. The direct-current transmission converter valve cooling water quality online monitoring system and method are mainly used for monitoring water quality in a direct-current transmission converter station and related fields thereof to avoid the problem of scale formation of a cooling tower due to low water quality. A water sample to be detected is delivered to a special water quality analysis groove through a sample delivering pump, water quality is detected through instruments such as a thermometer, a conductivity meter, a hydrotimeter and a total alkalinity meter, results are transmitted to a data acquisition analyzer, and are calculated by built-in data analysis software, and states of the water sample are locally displayed or submitted to an upper computer. The system is easy to operate, visual in detection result and high in adaptability to detection environments, not only can be used for static detection, but also can be used for real-time online monitoring. By the method, common workers can rapidly take measures to solve problems conveniently.

Description

technical field [0001] The invention relates to a monitoring system of a direct current transmission system, in particular to an online monitoring system and a monitoring method for the cooling water quality of a direct current transmission converter valve. Background technique [0002] The converter valve is the core equipment of the DC transmission project. By sequentially connecting the three-phase AC voltage to the DC terminal to obtain the desired DC voltage and realize power control, its value accounts for about 22-25% of the total price of the complete set of equipment in the converter station. . [0003] The design of the converter valve applies the latest technology and research results of power electronics technology, light-controlled conversion technology, high-voltage technology, control technology and pressure equalization technology, cooling technology, and high-voltage insulating materials. The main technical difficulty lies in: the converter valve temporarily...
