[Abstract]The power system real-time dynamic monitoring sub-station is the main component of the wide-area measurement system, which can output accurate and complete data. Under the condition that the power line network is more and more extended, the real-time monitoring sub-stations of the power system will inevitably require further stricter operation standards. Then, in specific actions, it is necessary to first elaborate on the real-time dynamic monitoring sub-stations of the power system and their significant effects, and then discuss the technical points of the real-time dynamic monitoring sub-stations, and finally, the impact of these technical operations The factors are analyzed and the corresponding prevention and control countermeasures are summarized, so as to ensure the elimination of these influencing factors, and also help the long-term stable development of the power system.
