The energy conversion process of the WSE 1300i is described in part by the system block diagram below. The wind turbineproduces 3-phase AC power which is first rectified to an unregulated DC state. The DC/DC power semiconductor bridge then inverts DC to AC to allow DC/DC conversion through a high frequency transformer. A Relay-based multiplexor engages any
one of multiple step-up or step-down confi gurations in the high frequency (HF) transformer. Depending on the rectifi ed voltage, the transformer confi guration is selected to allow an optimized
voltage transformation. This allows for a very wide range of input voltages to be transformed and maintained at an optimal level for the final exporting step. This final step completes the exporting of
power in the form of 60 Hz true sinusoidal current synchronized to the 120 V grid.

User Interface
The user interface is depicted below and consists of a two line LCD display, blue Power LED, green Exporting LED, a red Error LED and four buttons for menu navigation.

The setup of a typical WSE 1300i installation is shown below. The installation must comply with the National / Canadian Electrical Code and local utility codes. This applies to conduit, conduit fittings, wire size (minimum of 14 AWG) and wire performance (90°C). An AC-disconnect with over current protection (120V, 15A – such as a dedicated circuit breaker) will also be required between the inverter output and 120V 15A branch service. When selecting these components keep in mind that the WSE1300i inverter is designed to operate in a controlled (weatherproof) environment that is well ventilated and shaded.

Operation
Synchronization
Once powered, the WSE 1300i inverter will perform a self check of its systems and then attempt to verify that the grid is stable. This period is indicated by a green blinking Exporting LED and
a timer display on the LCD (Figure 7). Then, if over a period of five minutes the grid is adjudged to be stable (120 V and 60 Hz nominal), the inverter will engage the turbine and immediately
allow the export of power |
|
Normal Operation
Weather permitting, the WSE 1300i inverter will export power. This is a normal operation mode that is indicated by a stable green Exporting LED and an LCD display of the exported power
level. In the weakest of wind conditions, the Exporting LED goes out and the inverter goes on stand-by. When windier conditions resume the inverter will immediately resume exporting power. |
|
Performance Monitoring
The menu interface allows the user to inspect the energy Export History in kWh for a number of different periods: Last hour, 24 hours, 7 days, 30 days or Lifetime. To access any of these displays, press the back button to exit the status screen and the down button and enter button to enter the Export History submenu. Using the up and down buttons, the user can cycle through the export histories for the periods above. An example of an Export History display is given in Figure 9. All export histories are updated in real time and displays will persist for thirty seconds before returning to the current status (due to button inactivity). |
