and event-triggered reports can be configured to query real-time
and historical data. Periodic reports can be set up for hourly, shift,
monthly, etc. Event-driven reports can be configured to record
start/end time, duration, time-stamped max/min values, etc., and
triggered by a digital point.
Fault Detection and Diagnostics
Fault detection and diagnostics is central to system stability
and reliability. When a problem occurs in the system, the fault
detection and diagnostic function of the OC 6000e can quickly
analyze the cause of the failure by examining historical data and
sequential SOE event records. This allows maintenance personnel
to pinpoint the cause and location, and to determine a response.
The system detection and diagnostic software monitors the
status on several levels:

Engineering Tools
Standard configuration tools allow quick and easy configuration
of control, reports and displays. A standard set of engineering
configuration tools is provided with the system. Tools consists of:

State-of-the-Art Control Solutions
Proven control solutions allow precise control over the entire
operating range and are the foundation of safe and efficient
operation. The OC 6000e DCS provides a suite of integrated
control solutions for safe and efficient unit operation. Solutions
include plant-wide control, such as boiler control, turbine control,
furnace safety supervision, sequential control, electrical control
and balance of plant.
Modulating Control System (MCS)
MCS controls the operations and process parameters of each
system such as fuel, air, gas, water, and steam. The MCS
accomplishes this by applying a coordinated control scheme
and advanced control strategy.
Coordinated Control System (CCS)
CCS is the main controller of the unit. Based on the dispatching
demand, CCS adjusts thermal process to meet the demand.
There are four modes of operation; namely coordinated control,
turbine follow, boiler follow and manual operation. The unit can be
