Giới thiệu |
Distributed Energy Resource (DER) systems are
small-scale power generation technologies (typically in the range of 3
kW to 10,000 kW) used to provide an alternative to or an enhancement of
traditional electric power systems. Wind energy is one of the major
power sources for DER, especially for standalone power generators within
a smart grid system. One of Taiwan’s leading smart grid projects is
working to integrate wind energy systems to develop a complete system
with an excellent cost/performance ratio. They
turned to Advantech for a solution which could deliver pitch control,
hydraulic system monitoring and wind turbine control. |

Yêu cầu hệ thống |
To provide easy maintenance and accessibility
through the web, our client needed a dedicated HMI device able to
manipulate the wind control system from the tower base and provide
real-time monitoring capabilities. Furthermore, the integrator required a
reliable and compact PAC controller that could receive wind
speed/direction analog signals from an anemometer to direct the nacelle
and rotor blade in order to catch the optimal wind direction. They also
wanted to program a pitch control algorithm using SoftLogic to slow the
blades from moving too fast in the event of high winds or abnormal
vibrations from the wind tower. Furthermore the relative devices used in
such kind application utilize CANopen as the standard communication
protocol, so compatibility with the software was important.

Mô tả hệ thống |
APAX-5521KW combined with APAX I/O modules were
integrated into the wind control system to provide optimum control. As a
powerful PAC controller with embedded KW SoftLogic, APAX-5521KW is the
best platform to provide real-time deterministic execution of
complicated pitch control application. Furthermore, it takes advantage
of one CANopen interface and one LAN ports to offer communication
ability with other devices. The APAX-5080PEC high-speed counter module
provides accurately encoded A/B/Z signals from wind yaw and rotor
blades. Through APAX-5060, 12 channel relay output can be connected to
the hydraulic system to control the yaw and rotor blades.

Kết luận |
Electrical rotor blade adjustment has come to be a
standard feature for modern wind energy plants. Not only does it offer
significant advantages for the pitching systems, but also ensures the
wind turbine operates at optimum yield under all weather conditions.
Advantech APAX offers an integrated, scalable and modular control system
for this wind turbine control system.
