Automated Plant Startup and Shut-Down System
Overview
As one of the world' s leading plant manufacturers, Mitsubishi Power has delivered a large number of plants from small-size industrial boilers and turbine plants to large-size monotube boilers and gas turbine combined cycle plants.
An automatic plant control system offers an automatic operational guide for starting up and shutting down a plant safely and efficiently by combining Mitsubishi Power' accumulated design know-how and operational techniques with the operational know-how of the user.
An optional operational guide is provided for the DIASYS series operator stations (OPS).
Functions
Automatic Operational Guidance for Startup and Shutdown of a Plant
The startup and shutdown procedures can be divided and managed by using multiple breakpoints (BP). Operation is possible after gaining a grasp of the startup and shutdown procedures.
In addition, the operation for each BP can be further divided into operation blocks. You can check the completion status of each block accurately.
As an operation guide for each operation block, a check list for confirmation and operational items is displayed. By following the operation guide (check list), you can start and shut down the plant reliably.

Plant Startup and Shutdown Curves to Facilitate Understanding of the Situation
You can monitor the difference between the planned and actual startup or shutdown curves. You can perform reliable operations and can take the appropriate action when a failure occurs. Actual data is traced along the planned startup or shutdown curve so that you can understand the difference between the planned and actual values on a trend graph and can perform quick corrective operations.
Types of Plant Startup and Shutdown Curves
- Ignition - safety valve test (COLD: after regular inspections)
- Ignition - turbine venting (COLD: after regular inspections)
- Injection - startup completion (COLD: after regular inspections)
- Ignition - startup completion (COLD: daily use)
- Ignition - startup completion (WARM)
- Ignition - startup completion (HOT)
- Ignition - startup completion (VERY HOT)
- Start of lowering - shut down of auxiliary equipment
Modes of Plant Startup and Shutdown Curves
On startup | COLD (After regular inspections or daily use), WARM (2 modes), HOT (2 modes), VERY HOT |
---|---|
On shutdown | Stop for 4 hours, Stop for 6 hours |
