performs the core control and protection functions of a small steam turbine package. The application software is field configurable, allowing it to be configured and modified to meet site-specific requirements. Modbus communications also allow easy interface with a package PLC or plant DCS.
The 2301E-ST has four operating modes:
Has multiple dynamics flexibility. Will work on pumps or compressors. Has capability for remote 4–20 mA speed reference through configurable analog input.
Isochronous Load Sharing
Is compatible with most existing analog load sharing speed control systems. Now with soft load and unload capability.
Droop Base Load
Adjustable load control using discrete raise and lower contact
Isochronous Base Load
Provides constant load level operation against a utility bus. The load setting may be fixed orchanged using discrete raise and lower inputs or a remote 4–20 mA input.
The following functions can be configured, depending on application requirements:
Manual, Semi-Automatic or Automatic Start Sequencing
Remote Speed Control
Isochronous Load sharing with soft load / unload transfer
Droop Load Control
Actuator Feedback Droop Control
Synchronizer Bias Signal Input
Power sensor Input (CTs, PTs)
Self-Powered Actuator Option
The 2301E-ST Hardware includes:
1 Load Sensor
3 PT Inputs, 3 CT Inputs
1 Actuator Driver
2 MPU Speed Sensor
1 Configurable Analog Output
2 Configurable Analog Inputs
8 Discrete (Switch) Inputs
