Concrete enforcement
Below in conjunction with accompanying drawing the utility model is further described:
Will comprise conversion of signals and isolated location, high-speed data acquisition card and industrial computer in conjunction with Fig. 1 native system, described conversion of signals is connected with high-speed data acquisition card with isolated location, and high-speed data acquisition card is installed on industrial computer inside and is connected with industrial computer.Described industrial computer is connected with protected location with the I/O unit of high voltage static reactive power compensator respectively; Described industrial computer is connected with the DSP processing unit by serial ports; Described high-speed data acquisition card is the PCI-6220 of NI company; Described industrial computer is selected the IPC-610H that grinds China for use.
The operating process of present embodiment is:
The SVC supervisory control system mainly comprises the five functional module: signal processing and data acquisition module, real time data are calculated display module, historical data and failure logging enquiry module, thyristor monitoring and protection module, switching value input/output module.Can finish following function: gather the also running status of display system in real time; Online judgement system failure state; Record important system operation information; System's long-time running state analysis, formation voltage quality, harmonic content analysis report; Record ripple echo assists installation personnel to check system mode etc. fast during the system debug.
Install at first acquisition system real time data, send into real time data after the line data of the going forward side by side conversion and calculate display module, parameters such as the current voltage of the system that calculates, electric current, meritorious, idle, power factor, harmonic wave state, then these data are shown in main interface, simultaneously these data are drawn in the real-time curve interface, be convenient to debugging and maintenance.Can inquire about system's real time data and the fault message stored in the historical data interface, the user can print concrete parameter according to self needs.In addition, SVC supervisory control system and DSP processing unit carry out real time communication, upload the operating state of up-to-date thyristor valve group by the DSP processing unit, when the thyristor valve group breaks down, can show concrete fault branch and fault type in silicon Stateful Inspection interface, the DSP processing unit is also uploaded information such as TCR electric current, trigger angle, valve group temperature simultaneously.The faulty indication interface can show the fault of all valve group sides, also receives the fault message that protected location sends simultaneously, shows in the lump when other fault occurs.When the SVC supervisory control system receives that catastrophe failure appears in the fault message of protected location and the system that judges; can pass switching commands for controlling switching value output unit excision high-tension apparatus down; with the high-tension apparatus of protection major loop, for the safe operation of SVC device provides powerful guarantee.
Figure 2 shows that high voltage static reactive power compensator monitor system software flow chart, carry out the programming of SVC supervisory control system, two important design concepts are arranged, be i.e. " program function determination procedure structure " and " data flow " with LabVIEW.Because the LabVIEW program is the sub-VI by a plurality of structures of multilayer and interface model unanimity to interconnect, nestedly constitute, each sub-VI is a packaged VI, finish certain function, so the division of determining in fact to depend on program function of program structure; Simultaneously, connect by " data flow " between the different sub-VI, and data flow is the process object of sub-VI, and determined the flow process of program, therefore, determined the content and the direction of data flow, also just determined the function and the structure of program.Tens sub-VI have just been used as the system voltage processing module among Fig. 2, the corresponding sub-VI of each part finishes function corresponding, be submodule important in the whole procedure, and the manufacture method of other module such as modules such as fault warning, storage and printing, switching value operation is also similar with it.In addition, for improving system real time, on communication protocol and strategy, taked following measure: adopt short frame structure,, simplify message structure as far as possible, reduce the unnecessary information transmission of intermodule satisfying under the reliability prerequisite; The timing cycle transmission combines with changing transmission, reduces degree of transitivity.System operational parameters is adopted periodically transmission, on off state is adopted the mode of just transmitting when changing.
