6 1.4.2 HIGH-POWER TURBINE The architecture of a wind generator is shown in Fig 2.4, where the complexity of the system is easy comprehensible. Because of the high power, many elements must be present in order to optimize the generation process; very important, are Pitch and Yaw subsystem, to maintain the wind turbine in the correct direction, and to optimize the attack angle to obtain the maximum power from the air. Fig. 2.4 High power Wind turbine parts These subsystems are sophisticated and increase the cost of the whole system. Ver /10/15 13 of 70

7 1.4.3 LOW-POWER WIND TURBINE The low power components for independent applications in homes or similar applications (as opposed to wind farms) have the following characteristics: No pitch No yaw No gearbox No mechanical brake Optional: charge regulator The DL WIND A1G Trainer incorporates a 12V, with three blades. Its characteristics are indicated on a separate page. The rate of flow of the Wind undisturbed by obstacles can be expressed using the appropriate scale, present in the following table. 1 m/s = 3.6 km/h = mph = knots 1 knot = 1 nautical mile per hour = m/s = km/h = mph Wind speed scale Wind Speed at 10 m Beaufort Wind height scale m/s ( Calm knots) m/s ( Light knots) m/s ( Light knots) m/s (7 11 knots) 3 Light m/s ( Moderate knots) m/s (17 22 knots) 5 Fresh m/s (22 28 knots) 6 Strong m/s (28 34 knots) 7 Strong m/s (34 41 knots) 8 Gale m/s (41 48 knots) 9 Gale m/s (48 56 knots) 10 Strong Gale m/s (56 65 knots) 11 >34 m/s (>65 knots) 12 Hurricane Fig. 2.5 Small power Wind turbine 14 of 70 Ver /10/15

8 2.9 DL 9013G3D MODULE DL 9013G3D module is a grid tie power inverter. The main difference between a standard power inverter and a grid tie power inverter is that the latter ensures that the power supplied will be in phase with the grid power. The grid tie power inverter can transfer wind energy from wind generators directly into the home grid using no extra equipment. It can be connected to any outlet (conventional network) in the home. The grid tie inverter controls the phase and the frequency and voltage of the power generated by the wind generator. It produces a pure sinewave and matches that of the grid. This model grid tie has build in bridge rectifier and dump load controller, it can maintain any rotating speed of the wind blades and keep the voltage from the wind turbine always at the range of the rated range of the grid tie inverter. It also has a high voltage protection function, when the wind is too big and the dump load controlling system can't keep the output voltage from the wind turbine, the controller will disconnect itself from the wind turbine. Another protection function is called Island Protection. If there is no AC voltage grid detected, for example when the grid is in maintenance or failure, the inverter will not put out power. The red LED will be lighted and the energy generated by the wind turbine is dissipated on resistance called Dump. When the mains becomes available, the inverter automatically exits from protection mode. Following the logic diagram of control. 42 of 70 Ver /10/15

9 The DL 9013G3D module is the heart of wind power generation system. It performs several functions inside. In input, he three phase AC voltage generated from the wind turbine is converted into DC voltage by the diode bridge and then stabilized by the DC DC converter. In output, the DC voltage is converted into AC voltage by inverter. The output value of AC voltage must be equal to grid mains. To obtain this are used control circuits like Sensing & Scaling, PLL controller and PWM controller. The protection block is used to monitor the internal parameters and it is activated in case of overload, high temperature, failure and grid mains OFF. The low pass filter block is used to remove low frequency noise LAYOUT 1) Connectors for the aerogenerator 2) Connectors for the AC voltage 3) Connector for ground 4) Connectors for dump resistor 5) Alert led 6) Status led 7) Fault led Ver /10/15 43 of 70

12 Adjust the number of motor revolutions through the knob %. The speed of motor simulates the wind speed that would do spin the blades of aerogenerator. Set the speed of motor to 50%. The green LEDs on the DL 9013G3D module indicate that you are generating energy. In this configuration we have connected two instruments of measurement. On DL 9030 display is shown the power flow in grid. - P > 0 the system releases energy in grid - P < 0 the system takes energy from grid On DL 9022 display is shown the total power generated from system. So check the values shown on two displays. They are the same. P grid = P gen Now we will simulate a load on the network. Turn ON the dichroic lamp by the power switch. So check the values shown on two displays. They are different. P grid < P gen P grid < 0 Now we will simulate the highest of wind, so set the speed of motor to 100 %. So check the values shown on two displays. They are different. P grid < P gen P grid > 0 Now we will simulate the disconnection of grid, so put the power switch of DL 9031 to OFF. Note that the lamp does not stay ON although there maximum wind. This because the system, for the safety rules imposed, if it is not connected to the grid enters in the protection mode and does not generate energy. Ver /10/15 69 of 70
