A perturbation source for in situ parameter estimation applications

Abstract: Abstruct-This paper describes a perturbation source for in situ parameter estimation applications for apparatus such as motors, transformer windings, etc. The system topology comprises two basic components, namely a digital-to-analogue (D/A) converter and a controllable bi-directional current source. The D/A converter is computer controlled and features an onboard transputer which generates control signals for the current source. The current source employs a half-bridge topology with MOSFET switches and a bloc… Show more

“…The PRBS is however not suitable as a perturbation signal for transformers due to a possibility of injecting low frequency components that would cause core saturation. This particularly occurs when a long PRBS is used [25]. The main contribution of this work, therefore, includes the following:…”

“…To reduce the effect of noise on the impedance measurement, a signal of sufficiently large amplitude can be injected into the power system. Excluding the injection of a single sinusoidal signal utilized in frequency-scanning techniques, impulse injection and pseudo-random binary sequence (PRBS) injection methods were proposed in [12] and [13], respectively. Their injection by means of a three-phase gridconnected inverter and corresponding analysis in the sequence domain have been recently demonstrated in [14] for the impulse, and in [15] for the PRBS.…”
