IEEE 387-2017 pdf download.IEEE Standard for Criteria for Diesel Generator Units Applied as Standby Power Supplies for Nuclear Power Generating Stations
1.1 Scope
This standard defnes the criteria for the application and testing of diesel-generator units used as Class 1E standby power supplies in nuclear power generating stations.
Figure 1 shows the boundaries of systems and equipment included in the scope of this standard.
1.2 Purpose
This standard provides the principal design criteria, the design features, testing, and qualifcation requirements for the individual diesel-generator units that enable them to meet their functional requirements as a part of  he standby power supply under the conditions produced by the design basis events cataloged in the plant safety
analysis.
1.3 General
1.3.1 Inclusions
The following items are within the scope of this standard:
a) The diesel engine, which includes the following:
1) The fywheel and coupling (if applicable)
2) The combustion air system and supply
3) The starting system
4) The starting energy system
5) The fuel oil supply system (e.g., including the day tank, flters, piping, pumps, valves and strainers between  he day tank and the engine injection pumps)
6) The lubricating oil system
7) The cooling system (jacket water), starting at the point where the cooling medium is introduced to the diesel-generator unit
8) The exhaust system
9) The governor system
b) The generator, which includes the following:
1) The excitation and voltage regulation system
2) The diesel generator output breaker at the switchgear
3) The diesel generator grounding system
c) The local control, protection, and surveillance systems associated with the diesel engine, the generator,and their auxiliary equipment and systems cited above
d) The ac and dc distribution systems associated with the diesel engine including the battery (if supplied with the generator) for starting, feld fashing, the generator, and their auxiliary equipment and systems cited  bove, exclusive of the auxiliary power system beyond the generator output breaker
e) Fuel oil storage system (e.g., storage tank, transfer pumps, flters, piping, valves, and strainers between the storage tank and the day tank)
f) Cooling air and ventilation system
g) Those elements that are essential to the safety function of diesel-generator units within the scope of this  tandard (see Figure 1)
h) Evaluation of the characteristics of the service environment relative to performance and qualifcation
1.4 Inclusions for site testing
The following items are not in scope of the standard, but are included as they are required for accomplishing site testing purposes only, as described in Clause 7.
a) The ac and dc power distribution system, which includes the following:
1) Circuits for conveying ac power from the diesel-generator breaker up to and including the dedicated Class 1E bus
2) Circuits for conveying ac or dc power to the diesel-generator units and associated controls
3) DC power supplies (batteries and chargers), if dedicated to the diesel-generator unit
b) The remote and local control, protection, and surveillance systems, which include the following:
1) Devices for automatic and manual starting
2) Devices for load shedding and sequencing
3) Remote devices for the protection of the diesel-generator unit and its auxiliary equipment
4) Synchronizing equipment
1.5 Exclusions
The following items are not in the scope of this standard:
a) Diesel-generator unit enclosure and foundations
b) External service equipment and systems that are a part of, or that are housed in, the diesel-generator unit enclosure, other than those tabulated in 1.1.1
c) The control, protection, and surveillance systems for the following:
1) Protecting the loads energized by the diesel-generator unit
2) Prevention of common-mode failure between the preferred power supply and the standby power supply
d) Determination of the characteristics of the service environment
e) Fire protection system
