XJ Group develops precision load control system through technical appraisal

The appraisal committee reviewed the work report, technical report, new report, test report, and understood the project background, overall design plan, key technology research and product development, and watched the project results and the XJ Group's comprehensive R&D production capacity display. The appraisal committee fully affirmed the innovation and advanced nature of the “PAC-8901 Precision Load Control System” and the practicality and necessity of the product under the current grid situation. It was agreed that the system is designed with reasonable technology, advanced technology, and practicality. Qiang is a major technological innovation in the field of AC/DC hybrid power grid system protection. It meets the technical requirements for engineering applications and the overall technical specifications have reached internationally advanced levels.

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.
