Voltage/reactive power closed-loop regulation is achieved based on PID/fuzzy control algorithms, with built-in multiple safety mechanisms such as demagnetization protection, overexcitation limiting, and V/Hz limiting. For example, the UNITROL 6000 series adopts a dual-redundant CPU architecture, supports hot-swapping, ensures fault switching time <20ms, uses a modular structure, supports hot-swappable expansion, is compatible with ABB AC800M/S800 IO series buses, and can be seamlessly integrated with controllers such as PM867K02 3BSE081638R1 and PFSK162 3BSE015088R1. It is compatible with protocols such as IEC 61850, PROFINET, Modbus TCP, and DNP3, and can seamlessly interface with ABB 800xA DCS, S800 IO bus systems, and third-party PLCs (such as Siemens S7-1500). Typical interface configurations include fiber optic Ethernet, RS485/422, and hardwired I/O.
