WES30 Controller The control of the WES30 is based on a Industrial PC or IPC. This IPC based system acts like a PLC and has I/O modules in the control cabinet and a remote I/O unit in the nacelle. All sensors in the nacelle, switches, relays and the converter are wired to the I/O modules in the control cabinet. The IPC also runs an internal Ethernet LAN which connects the IPC to the I/O modules, the converter and the local control panel. The control panel is located on the control cabinet door for friendly user interface. The screen shows the actual wind speed, wind direction, rotor-speed and the generated power. It also provides the cumulative kWh production and the historical data. Using the buttons on the control panel, parameters controlling the behavior of the system can be changed. Some of these parameters can be set remotely over the Internet as well. The controller and the electrical system are 'fail-safe' designed, which means that in case of a failure the turbine goes in a safe position. The IPC logs detailed information about any failure. WES30 turbines are connected to the Internet. System log files, status reports, wind speed, the actual and cumulated performance can be monitored remotely. Each turbine can have it's own URL, login and password and can be reached through any Internet browser.
