AGC/AVC Control System

iTDR930 Series Integrated Protection and Safety Automation Device

The new-generation intelligent protection devices of the iTDR series feature a domestically developed, independently controllable software and hardware architecture, providing comprehensive relay protection solutions for generators, transformers, motors, capacitors, reactors, transmission lines, and other equipment in power systems. They also offer advanced stability‑control functions such as frequency‑voltage emergency control, oscillation separation, reverse‑power protection, anti‑islanding, and automatic frequency regulation, while incorporating smart capabilities like equipment health management, machine vision, and programmable logic.

iTDR961 Intelligent Measurement and Control Unit

The iTDR961 intelligent measurement and control unit integrates computer monitoring, data acquisition and processing, sequential control, five‑prevention logic, automatic quasi‑synchronization, and other functions into a single device. It acquires and processes various types of signals, implements programmable sequential control, and converts these signals into the formats required by the signal transmission system. It also transmits information to local data servers and SCADA monitoring centers. As a core component, it provides comprehensive monitoring, diagnostics, and control solutions for applications such as substations, distribution rooms, pumping stations, hydropower plants, and large industrial electrical equipment.
