Abstract

"MéTODO DE ESTIMATIVA". A invenção refere-se a um estimador de corrente de campo para estimar a corrente de campo em um aparelho síncrono excitado sem escovas que compreende um excitador que tem uma parte de estator e uma parte de rotor que compreende um retificador, e uma máquina que tem uma parte de estator e uma parte de rotor e um enrolamento de campo. O estimador de corrente de campo compreende: uma primeira unidade de cálculo, que calcula as voltagens (V~ ra~, V~ rb~, V~ rc~) da parte de rotor do excitador com base nos valores medidos da corrente (i~ s~) e da voltagem (u~ s~) da parte de estator do excitador, por meio de um modelo matemático do excitador, uma segunda unidade de cálculo, que calcula a voltagem (v~ ff~) do enrolamento de campo com base na voltagem calculada (V~ ra~, V~ rb~, V~ rc~) da parte de rotor do excitador, por meio de um modelo matemático do retificador, e uma terceira unidade de cálculo, que calcula a corrente de campo (i~ ff~) do enrolamento de campo com base na voltagem calculada (v~ ff~) do enrolamento de campo, por meio de um modelo matemático do enrolamento de campo."ESTIMATE METHOD". The invention relates to a field current estimator for estimating field current in a brushless excited synchronous apparatus comprising an exciter having a stator part and a rotor part comprising a rectifier, and a machine having a a stator part and a rotor part and a field winding. The field current estimator comprises: a first unit of calculation, which calculates the voltages (V ~ ra ~, V ~ rb ~, V ~ rc ~) of the exciter rotor part based on the measured current values (i ~ s ~) and the voltage (u ~ s) of the exciter stator part, by means of a mathematical exciter model, a second unit of calculation, which calculates the voltage (v ~ ff) of the field winding based on at the calculated voltage (V ~ ra ~, V ~ rb ~, V ~ rc ~) of the exciter rotor part by means of a mathematical rectifier model, and a third unit of calculation, which calculates the field current (i ~ ff ~) of the field winding based on the calculated voltage (v ~ ff ~) of the field winding by means of a mathematical model of the field winding.
