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.
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 port to offer communication ability with other devices. The APAX-5080PEC high-speedcounter 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.
