It is reported that "PAC-8901 precision load control system" is an important part of the UHV AC / DC power system protection, through the overall allocation of power grid and load configuration, to achieve mutual interaction between the power supply, power grid, and user load, improve the UHV power grid failure Emergency response capabilities. The system is mainly deployed in regional substations and centralized load-removal stations and exclusive substations and power distribution stations for large power users. In the event of UHV system failures, especially DC faults, when the receiving power grid requires a large number of control loads, the classification of load resources is adopted. Graded and sub-regional management realizes the real-time and accurate control of the subordinate user's interruptable load directly from the co-controlling station, effectively reducing the social impact of the grid fault, and improving the power grid's fault defense capability.
