The invention discloses a real-time monitoring method of low-power
wind power converters during networking. By means of the method, the running states of multiple low-power
wind power converters can be monitored in real time, failures can be conveniently found and removed in time, all control
microcomputer modules can be controlled through an upper computer, the
converters do not need to be detached when instructions are regulated and issued, and operation is facilitated for users. During actual networking of low-power wind
turbine generators, usually various types of permanent
magnet synchronous power generators exist. By means of the method, one low-power
wind power converter can adapt to various types of permanent
magnet synchronous power generators, and cost and networking difficulty are decreased. The method is improved on the basis of the
MODBUS RTU protocol, the start and the stop of messages are quite conveniently judged, interrupt
processing can be conveniently conducted through the control
microcomputer modules and the upper computer which are in communication through serial ports, and the wind power converters are quite conveniently networked and connected with an industrial
personal computer, a PLC and other devices due to the characteristics and wide application range of the protocol itself.
