AND LOAD SHARING
Woodward interactive training module simulates look and feel of an actual
three-engine generator system
It can be a challenge to under- stand what is occurring when a generator breaker closes. With
that in mind, Woodward Inc. has
Woodward Inc. has released an interactive

tery out of generator synchronization and
Woodward Inc. has released two new electric actuators, the R- 11 and R- 30, to provide high- torque rotary travel for positioning various types
Weighing 18 lb., the electric actuators provide transient
torque rotary travel ( 8. 1 and 22. 1 lb.ft. respectively) at low
supply current ( 3. 2 Amp max.) while maintaining the fast
response needed to position various types of control valves
and other mechanisms in high-temperature, high-vibration
locations, the company said.
In reciprocating engine applications, these valves may
include fuel throttles, wastegates, exhaust gas recirculation (EGR), compressor recirculation (bypass), waste heat

recovery (WHR) and exhaust. Additional applications on
reciprocating engines include variable turbine geometry
(VTG) turbocharger actuation.
Both the R- 11 and R- 30 actuators accept a position
command signal from a controller to position the actuator’s
output shaft. Internal electronic feedback assures that the
output shaft moves precisely to the requested position.
The actuators accept a 4 to 20 mA, 0 to 200 mA or 24 volt
pulse-width modulated (PWM) command signal while providing a 4 to 20 mA output shaft position signal that external devices can use as direct feedback for the output shaft’s position.

The Power Generation Learning
Module takes the user through three-engine generator systems and shows
how they interact with each other, a
local load and the utility.
The training starts out by explaining
engine control and tuning, then moves
onto generator and power generation
fundamentals and progresses to isochronous and droop load control.
After explaining generator synchronization, it goes through various types
of load sharing between the generators and the utility, including droop
base-load to the utility; droop/droop
load sharing and isochronous load
sharing in isolated operation; isochronous base load against the utility; and
import/export control. The training
