DESCRIPTION

The General Specifications (GS) describe the features, functions, system configuration examples, engineering environment, software operating environment, hardware configuration, installation environment, and compliant standards of a turbomachinery controller using the STARDOM FCN autonomous controller, and outline the functions of turbomachinery I/O modules.
As for the FCN, refer to “FCN Autonomous Controller Hardware (FCN-100)” (GS 34P02Q12-01E), “FCN
Autonomous Controller Hardware (FCN-500)” (GS 34P02Q14-01E), “FCN Autonomous Controller Functions (FCN100)” (GS34P02Q01-01E) and “FCN Autonomous Controller Functions (FCN-500).” (GS34P02Q03-01E)

A flexible control system that can be installed with a variety of I/O modules including a turbomachinery I/O module.
An NFBU200 is used as the base module. In the configuration example below, a pair of turbomachinery I/O modules and four arbitrary I/O modules are installed in the base module in addition to the redundant CPU, power, and
modules.

Product parameter

● FCN-based Turbomachinery Controller
The FCN autonomous controller can be applicable to a variety of processes from sequence control processes to analog control processes. A wide variety of types of I/O modules are supported and a flexible system configuration can be selected according to purpose.
Applying an FCN-based turbomachinery controller to the control of generator turbines or other turbomachinery such as compressors also enables control of their ancillary facilities.
The CPU module, power supply, and communication can be made redundant for applications that require high reliability.
● Turbomachinery I/O Modules
Combined use of an FCN autonomous controller and turbomachinery I/O modules makes it possible to control and protect turbomachinery such as turbines and compressors. With the STARDOM turbomachinery controller, a flexible system can be constructed according to the scope of control and the installation space.
Of the turbomachinery control and protection functions, processing that requires high speed response is carried out by the turbomachinery I/O modules. There are two types of turbomachinery I/O modules: a servo module that performs high speed servo control in a cycle of 5 ms and a high speed protection module that performs a high speed protection action in a fast scan (5 ms) or a standard scan (10 ms).

APPLICATION

The primary functions of a turbomachinery controller comprise of regulatory control of the turbomachinery speed, load, and fluid pressure, and so on, and protection of the turbomachinery from anomalies. Control and monitoring of ancillary facilities can also be added if necessary.
● Configuration Types
There are two types of configuration for the STARDOM turbomachinery controller.
Type 1: Configuration with a short base module
Type 2: Configuration with a long base module
The following table shows a list of the functions of each configuration.

A compact turbomachinery controller consisting of an NFBU050 short base module and NFCP050 CPU module with built-in I/O and communication capability. Two turbomachinery I/O modules and one arbitrary I/O module can be installed.
