Inventor: CLARK DAVID ALAN
IPC: G01V3/08
Filed: 2008-06-18
Abstract: Locating and characterising a magnetised body involves moving a magnetic gradient tensor sensor relative to the magnetised body along a profile, or allowing the magnetised body to move along a profile past the sensor. Magnetic gradient tensor measurements are obtained at points along the profile. A rotational invariant calculated from the eigenvalues of the magnetic gradient tensor measurements is then used to locate and/or characterise the body. The rotational invariant can be the scaled moment of a point dipole representation of the magnetised body, or one third of the square root of the scaled moment. The rotational invariant is modelled and sufficient measurements obtained to over-determine parameters of the model. A system of linear equations resulting from a model of the gradient tensor elements is then solved using the determined values of parameters.

Title: Wind turbine generator and output power control method
Inventor: YASUGI AKIRA
IPC: F03D7/00
Filed: 2010-08-26
Abstract: A wind turbine generator (10) derives the gradient of a change in output power of a generator (20) that generates power by rotation of a wind turbine rotor (16), and determines an increase/decrease in the output power of the generator (20) on the basis of the derived gradient of the change in output power. Then, when the frequency of a utility grid (42) has dropped, power control is performed on the basis of the determination results. Therefore, a decrease in the amount of power supplied to the utility grid (42) can be more effectively compensated for by accurately detecting output power fluctuations of the generator (20), using a simple configuration.
