| Summary: | Positive and energy saving frequency control of submersible
asynchronous electric motors demands a research of its
work as a part of electrotechnical complexes of installations
of electrocentrifugal pumps on the basis of modeling. This
approach is oriented to development of ways of identification
of parameters of its equivalent circuits on experimental data. A
research objective is development of a way for determination
of parameters of the equivalent circuit of submersible
asynchronous electric motors with the use of integral of an
attenuation curve of current of a winding of the stator without
additional transition to frequency responses. The research of
a way is conducted on the basis of the developed installation
for identification of parameters of equivalent circuits of submersible asynchronous electric motors. For assessment
of reliability of a way and a technique of identification of
parameters of the equivalent circuit of the submersible electric
motor with integrated conversion of an attenuation curve of
current of the stator of the submersible electric motor the
experiment which shows the greatest discrepancy between
values of parameters of the equivalent circuit — no more than
10 % is made. The developed way of identification of parameters
of equivalent circuits of the submersible postrepair electric
motor, thus, allows to determine operational parameters and
characteristics of the electric motor in conditions of repair
service enterprises. |
