| titleOfInvention | Inertia control system for wind turbines |
| abstract | Inertia control system for the type of wind turbines that comprise a rotor (5), a generator (12) driven by the rotor (5) that interacts with a power converter (13) to generate electrical energy, a wind turbine controller ( 15) comprising a blade pitch change controller (19) and a generated power controller (18), a power converter controller (14) that interacts with the wind turbine controller (15), said control system inertia comprises: an inertia emulation block (17) to prevent distortion in the active power output after addition or subtraction of power proportional to the rate of change of frequency, which generates an additional power signal (32) , negatively proportional to the rate of change of frequency (23), characterized in that said value of the rate of change of frequency (23) of block (22) is entered in the additional power calculation block (24), where a block (27) first calculates the additional power value as a negative value of the multiplication of the rate of change of frequency (23) by a parameter Kinertiapar (25), which can be defined locally or communicated by an emulation element of inertia (20) in the wind farm controller (16), and by the squared value of the turbine rotation speed, which is measured by the converter control unit (14) and communicated to the wind turbine controller ( fifteen); the calculations of said additional power calculation block (24) can be disabled by means of the disable inertia signal (26) when a limit is reached, said additional power is added (28), by means of an output (31) and a computation of a block of additional power limitation (29) that limits this value by means of maximum and minimum configurable values, to a reference power of the wind turbine controller (15); said additional power (32) is previously limited in the additional power limitation block (29) according to a configurable parameter and the power not delivered, due to the limitation, is accumulated in an element (30) whose previous accumulated value (31) to the multiplication by a configurable constant it is added to the additional active power (28); and the reference rotational speed of the wind turbine controller (15) is adapted (47) in proportion to the change in frequency (21) divided by the nominal frequency and by Kinertiapar (25) and is adapted according to the grid frequency (23 ). |
