Background technology
The series capacitor compensation protection is adopted many parallel connections with lightning arrester; Require the arrester valve piece made characteristic consistent during parallel connection; If certain the arrester valve piece made characteristic is inconsistent or generation is aging; This post maybe be accidents caused, for avoiding taking place similar accident, needs series capacitor compensation protection is monitored with the lightning arrester state.The protection of development series capacitor compensation realizes the on-line monitoring and the lightning arrester action situation record of series compensation platform leakage current of an arrester, conducting electric current with the monitoring device of lightning arrester.Can analyze the running status of lightning arrester and the operation trend of lightning arrester through monitoring leakage current of an arrester waveform, in time find some defectives of lightning arrester, to reduce the generation of fault; Through record lightning arrester conducting constantly and waveform, the source of damage for electrical equipments such as transformer, switchgear, bus in the transformer station provides necessary basis for estimation.
The utility model content
The utility model provides a kind of series capacitor compensation protection to use the lightning arrester on-Line Monitor Device, has realized on-line monitoring and the lightning arrester action situation record of series capacitor compensation protection with leakage current of an arrester, conducting electric current.
The technical scheme that the utility model adopted is:
The lightning arrester on-Line Monitor Device is used in a kind of series capacitor compensation protection; Comprise FPGA module, primary processor CPU module, data acquisition module, HMI display module, FLASH storer; And power module; Said FPGA module connects primary processor CPU module through high speed parallel bus, and primary processor CPU module is connected with the HMI display module through the CAN bus, connects FLASH memory module and power module and data acquisition unit simultaneously.
Said FPGA module is given the communication receiving trap through Ethernet and optical fiber interface output data;
The specification of said communication receiving trap is 9-1 or the 9-2 agreement of IEC61850;
Said FPGA module further is connected with house dog and reset circuit.
The utility model series capacitor compensation protection has the following advantages with the lightning arrester on-Line Monitor Device at least: the utility model monitoring device can realize that series capacitor compensation protection uses the lightning arrester status monitoring; Can in time find the defect problem of lightning arrester; Avoid taking place Explosion of on Arrester, protection equipment and operations staff's safety, the generation of effectively prevention accident; Great economic benefit and social benefit are arranged, the monitoring of lightning arrester in the time of can being widely used in lightning arrester parallel connection protection.Monitoring device receives and handles the digital signal from collecting unit, handles the current analog amount input that electromagnetic transformer provides, and can take into account electronic mutual inductor and traditional mutual inductor mixing application simultaneously.Has 2 Ethernet electricity/light 100base-Fx/10Base-FL data-interface; After the data processing that receives from collecting unit; Send to transformer station's background monitoring system with the IEC61850 standard agreement; Realization meets the intelligent grid demand for development to the far-end monitoring and the unmanned of series capacitor compensation protection with the lightning arrester state.
Description of drawings
Fig. 1 is the structured flowchart of the utility model series capacitor compensation protection with the lightning arrester on-Line Monitor Device.
Embodiment
Below in conjunction with accompanying drawing the protection of the utility model series capacitor compensation is done detailed description with the lightning arrester on-Line Monitor Device:
See also shown in Figure 1ly, the lightning arrester on-Line Monitor Device is used in the protection of a kind of series capacitor compensation, comprises FPGA module, primary processor CPU module, data acquisition module, HMI display module, FLASH storer, house dog and reset circuit, and power module.Said FPGA module connects primary processor CPU module through high speed parallel bus, through Ethernet and optical fiber interface output data.Said primary processor CPU module is connected with the HMI display module through the CAN bus, connects FLASH memory module, house dog/reset circuit and power module simultaneously.
The data that data acquisition unit collects send the FPGA module of monitoring device to through optical fiber; The FPGA module is connected through high speed parallel bus with primary processor CPU module; Primary processor CPU module sends data to the FPGA module through high speed parallel bus after data are handled again; The FPGA module sends data to the communication receiving trap through Ethernet interface or optical fiber interface, the 9-1 and the 9-2 agreement of communication receiver module stipulations optional iec 61850.
After primary processor CPU module as shown in Figure 1 is carried out calculation process with the data that receive; Sending data to the HMI module through the CAN bus on one side shows; Another side screens data, and deposits outside FLASH storer in, analyzes so that read when needing.The capacity of FLASH storer is enough big, can store down enough data so that the user reads analysis.
House dog as shown in Figure 1 and reset circuit reset to primary processor CPU module when the program run of primary processor CPU module makes mistakes automatically, guarantee its normal operation.
HMI display module as shown in Figure 1 carries out data interaction through CAN bus and primary processor CPU module; When the user changes parameter on man-machine interface; The HMI display module sends the parameter of change to primary processor CPU module; Handle, store by primary processor CPU module, return to the HMI display module again.LED light on the HMI display module can be accurate and visual the operation conditions that indicates the monitoring analysis unit, simultaneously can also write down corresponding SOE incident, so that the user inquires about logout.The HMI display module can also let primary processor CPU module that the data of FLASH storer are read through the CAN bus, the action waveforms the when leakage current of the real-time monitoring of demonstration lightning arrester, wave recording data, record lightning arrester action frequency, lightning arrester action etc.Monitoring device and upper machine communication adopt IEC61850 form (optional 9-1 and 9-2).
The above is merely a kind of embodiment of the utility model; It or not whole or unique embodiment; The conversion of any equivalence that those of ordinary skills take the utility model technical scheme through reading the utility model instructions, the claim that is the utility model contains.
