Description
Product Overview
The ABB PPD113B01-26-111000, order code 3BHE023784R2630, is a high-performance process controller core module for ABB AC800PEC platform, widely deployed within ABB UNITROL generator excitation control systems. It executes high-speed closed-loop excitation regulation, generator voltage control, reactive power regulation and system interlock protection. This controller handles fast dynamic sampling and real-time computation for synchronous generators in thermal power, hydropower plants and gas turbine power stations. It is a critical aftermarket spare for maintenance and retrofit of existing UNITROL excitation systems.
