Embodiment
Referring to Fig. 1, the integrated monitoring system of the electrical power generators state in the present embodiment, including field control cabinet 6, in
Heart control room 1 and excitation system 10, excitation system 10 include 5 excitation units 11, and excitation unit 11 is controller and power list
First integral structure, easily switching, can carry out switching undisturbed and the maintenance that do not have a power failure.Field control cabinet 6 passes through cable 9 and excitation
System 10 electrically connects to realize the control of IO input and output.Excitation system 10 gathers generator operation data and handled, and leads to
TCP transmission control protocol 8 is crossed to transmit generator operation data to four in central control room 1 with 16 2K speed
Man-machine interface 2 and the running status for showing generator in real time, meanwhile, service data is stored in the storage list in excitation unit 11
Member, to facilitate failure logging and analysis, instead of by oscillograph, power analyzer and a large amount of sensor groups into monitoring system
System, it is to avoid point multiple pictures, observation and analysis failure all inconvenient defects.
Specifically, man-machine interface 2 of the controllers on four computers in central control room 1, in human-machine interface
Principal and subordinate's working condition of five excitation units 11 in excitation system 10 is set on mouth 2, and man-machine interface 2 is all touch screen, control
Personnel only need to set excitation parameter at interface by way of touch, it is not necessary to hard operation button, easy to operate, substantially increase
Service life and reliability.Then by 5 11 points of excitation units it is main frame, standby host and 3 according to the different of principal and subordinate's working condition
Slave 5 and the communication of data is carried out each other by the parallel connection of CAN 4, wherein main frame passes through the electricity of cable 9 with field control cabinet 6
Connection, excitation unit 11 is dual-cpu structure, and the two-ways cpu unit 7 that main frame and standby host pass through passes through TCP transmission control protocol 8
Modbus agreements and udp protocol carry out the data processing of high speed and four computers being uploaded in central control room 1
On man-machine interface 2, three slaves 5 are connected with four personal-machine interfaces 2 respectively by Ethernet 3, three slaves 5 for intelligence
Stream, the working method that excitation system 10 is set is many from redundancy protecting mode, and protected mode maintenance is changed more quick, had
Effect ensure that effective operation of generating.Two-ways cpu unit 7 is by the modbus agreements of TCP transmission control protocol to generator
Excitation con-trol is carried out, the three-phase voltage of generator and the waveform of three-phase current then use the udp protocol of TCP transmission control protocol 8
Transmitted with 0.5ms, 40 points of each sine wave speed to each man-machine interface 2, man-machine interface 2 shows generator output wave in real time
Shape, load and the failure situation of generator can be conveniently and efficiently analyzed simultaneously, traditional excitation simple function is changed, realizes
