Advanced Training Course on New Power System Relay Protection: Standard Implementation, Setting Calculations, Intelligent O&M, and Analysis of Typical Accident Cases

Notice on the Advanced Training Program for Implementation of Relay Protection Standards, Setting Calculations, Intelligent Operation and Maintenance, and Analysis of Typical Accident Cases in New Power Systems

To all relevant enterprises:

In China, new energy installed capacity now exceeds that of traditional power sources, altering fault patterns in the power system. Inverter-based generation, bidirectional power flow, and weak-grid conditions pose adaptation challenges for conventional protection systems. Meanwhile, a wave of new national and industry standards for relay protection, alongside updated cybersecurity regulations for power monitoring systems, are being rapidly implemented. Technologies such as intelligent operations and maintenance (O&M), SCD virtual circuit management, AI-driven fault identification, and digital twins are accelerating adoption.

The field faces significant engineering challenges, including difficulties in coordination settings for new energy stations, detecting hidden defects in virtual circuits, downstream fault escalation on the user side, protection anomalies triggered by peak-shaving or operational mode switching, and cybersecurity compliance risks. To help professionals master new standards, solve complex setting calculation problems, and enhance intelligent O&M capabilities and accident analysis skills, we are launching this advanced executive training program. The program focuses on practical engineering applications, in-depth analysis of key challenges, and case study discussions.
