Studying Transient State Using State Parameters
Journal Title: Acta Marisiensis. Seria Technologica - Year 2017, Vol 14, Issue 1
Abstract
This paper presents the state variables method in the analysis of the transient state. Using this method the behaviour of transformers at on/off switching is studied. The transient state is a short event caused by any changes in the system which is followed by an energy modification stored in the system. The energy is stored in capacitors and coils and any modification needs time and has reactions. These reactions can be high impulses of energy which propagate through the network and influence or even destroy other circuit elements or devices. The transient state of an RLC circuit and of a transformer is studied. Differential equations are used and the nonlinearity of the coil is highlighted. Differential equations and the equivalent circuit are used to deduce the state parameter model for the transformer. Equations and equivalent circuit for a real transformer are deduced with and without load at the output. The behaviour of the transformer was studied while functioning in an open circuit and with different loads at the output. To study the output parameter variations state space model simulation was used
