DRS-CCI - Emergency Diesel Generator Controls System
From Commercial Nuclear
The DRS Consolidated Controls Voltage Regulator and Speed Controller are designed for Class 1E (including Class 1E seismic requirements) safety related nuclear applications. The speed of large diesel engines must be kept within an ideal engine-specific range. Both excessive speeds and speeds which are too low must be measured and controlled reliably. The generator voltage must also be measured and controlled reliably.
Together with an Emergency Diesel Generator (EDG), the DRS-CCI Digital Voltage Regulator and Speed Controller enable safe and seamless operation of the power plant in the event of loss of on-site power.
The PLµS 32 EDG Control System was designed for Class 1E systems. It has over a million hours of safety critical plant operations.
