EP Control Systems ensure the safe
and efficient operation of electrostatic precipitators and
their various parts. Doosan designs, develops and supplies
a variety of control systems (EP Monitoring System, Dust Concentration
Monitoring System Panel, EP Control Panel, Sub Panel, SI-TR
Control Panel & EP Distribution Panel) that are used for
monitoring and controlling electrostatic precipitators. |

| - System
Structure and Characteristics |
| |
• EP Monitoring Systems (OIS System)
display and control EP operation
conditions,
such as the level of dust concentration in EP input/output
modules,
boiler load and real time
trends.
• EP Control Panels manage the operational
conditions through a PLC, while
maintaining
optimal control and monitoring functions through data
communication
with the SI-TR/DCMP. |

| - KEY Interlock
System |
| |
• The key interlock system is installed to
protect operator safety when entering the electrostatic
precipitator for maintenance and repair. The MCCB key
operates via an interface device in the “Main Key Exchange
Box” of the MCCB key, located at the grounding attachment
(Grounding System) of the precipitator manhole and SI-TR.
It also functions to prevent safety hazards by blocking
pulse energization when the manhole is open.
Other facilities include a: Local Control System
for localized operation of the rapper, seal fan and
vibrometer; Dust Concentration Monitoring System to
measure and control dust concentration capacity at
the electrostatic precipitator input and output modules;
“Hopper Level Switch” to monitor the level of the
Hopper.
