BoxGovernor 3Vd/2Vd

Overview

BoxGovernor 3Vd/2Vd

"Box governor 3Vd/2Vd" from MHPS is a system specialized for steam turbine control. A control application for a wide range of steam turbines can be built flexibly based on users' needs.

MHPS offers a highly reliable system only a leading plant manufacturer can offer in order to contribute to our customers' success.

Features

  • Maintaining availability with online maintenance
    You can update various parameter values from a user interface without stopping a currently operating governor.
    Control functions other than the modified part are not affected, and the availability of the facility can be maintained.
  • Self-diagnostics for failure detection
    "Box governor 3Vd/2Vd" has self-diagnostic functions for failure detection. These include a watch dog timer and a power supply monitoring function.
    In addition, disconnection of the actuator output can be detected, and this can be used to build logic for handling the problem in accordance with the plant management.
  • Extended resolution for communication contention
    "Box governor 3Vd/2Vd" supports resolving communication contention with other control units from MHPS or third parties. (There is a delivery record of this feature with Modbus/TCP.)

System Configuration

System Configuration

The system configuration including the turbine to be controlled is shown in the diagram above.

A box governor 3Vd/2Vd consists of a "user interface" and a "control unit". The "user interface" is a 15-inch LCD touch panel used for monitoring and operation. Users can customize the screen flexibly as required. The "control unit" is a controller with an Intel CPU used for steam turbine control (data processing and signal input/output processing). When you install a "user interface" and a "control unit", they can be either combined or separated.

In addition to basic functions, a control application supports adding custom-made functions according to customers' needs.
