ABB AC800PEC | PPD513 A20-110615 | PP D513 | Excitation system controller

ABB AC800PEC PPD513 A20-110615, alternatively marked PP D513, is an excitation system controller built on ABB AC800PEC high performance real-time control platform. It acts as the main control processor for synchronous generator static excitation systems and is extensively applied together with ABB UNITROL excitation equipment on thermal, hydro and gas turbine generator units.

Equipped with CPU and FPGA heterogeneous architecture, this controller supports high-speed closed-loop control to satisfy rapid adjustment demands for automatic voltage regulation, power system stabilizer and reactive power management. It is equipped with fiber isolated high-speed I/O bus, Ethernet and Profibus DP communication ports, offering outstanding electromagnetic interference resistance to adapt to severe operating conditions inside power plant control cabinets. The controller operates on 24VDC power supply and supports DIN rail installation, with operating temperature ranging from -40°C to +70°C. Configuration and programming are carried out through Compact Control Builder AC800M software, which supports automatic code generation based on Simulink models.
