APPLICATIONS
The 2301E-HT for Francis Turbines is a standard off-the-shelf control system designed to control small Francis turbines.
This turbine controller contains specially designed algorithms and logic to start, stop, control, and protect the turbine.
With two serial communication ports, users can easily connect the 2301E-HT to a plant or process control system.
The controller’s inputs, outputs and status can be monitored and all start/stop or enable/disable commands can be issued via industry standard Modbus® RTU.
The controller can be configured in the field using Control Assistant software installed on an external PC.
Description
The control is housed in a sheet metal enclosure for general premises and consists of a single printed circuit board.
The 2301E-HT controller is designed for turbine control.
It includes three PID controllers (offline, online and load), startup routines and a variety www.abb-drive.com of protection functions (overspeed, etc.) that can be configured by the user to meet the requirements of a specific turbine application.
The 2301E-HT can be configured by the user to use different PID controllers, start-up routines, discrete and analogue I/O functions without the need for a dedicated control engineer.
The 2301E-HT controls the speed and load of a Francis hydraulic turbine in a generator application with a single gate analogue output.
