Converter Station Monitoring System SER Optimization Technology

In the context of the demand for large-scale clean energy grid connected transmission, the development of flexible DC transmission projects in China has been accelerated, and the controllability of flexible DC transmission projects for power transmission has been further enhanced. In addition to the process control of power production and transmission, the control of power electronic devices such as converter valves is added, which increases the number of control objects and expands the scale. In order to ease the monitoring work of operators, the coupling relationship between devices and the hierarchical relationship of alarms are analyzed from the primary device model and connection relationship, so as to facilitate the analysis of abnormal alarm information.
