This invention designs a full set of communication protocols and an encoding mode between the HVDC converter valve thyristor level and a valve base electronic device and proposes a counting method for operation state information of the thyristor level by the valve base electronic device and relates to a fault information judgment strategy to prevent the information of a gate unit from misreporting.
Description
Technical field
The present invention relates to high voltage direct current transmission (HVDC) field, particularly a kind of method for monitoring of novel HVDC converter valve thyristor level operation conditions.
Background technology
In high voltage direct current transmission, current conversion station utmost point control system, converter valve valve base electronic equipment and thyristor level gate pole unit constitute the whole secondary supervisory control system of converter valve.Gate pole unit monitors one-level thyristor, and the running status of this thyristor of real-time report valve base electronic device level.Valve base electronic device gathers all gate pole unit informations, reports utmost point control system after the comprehensive judgement.The system command of valve base electronic device receiving pole control simultaneously is to gate pole unit transmitting control commands.
The present invention proposes a kind of a complete set of monitoring strategies at converter valve thyristor level that is applied on gate pole unit and the valve base electronic device.This strategy has been stipulated a complete set of communication protocol, the coded system between thyristor level and the valve base electronic device, propose the multiplexing read data mode of a kind of bus and added up thyristor level running state information, and reported the fault message determination strategy of a kind of timing counting that adopts for the information that prevents the gate pole unit by mistake.This method for monitoring is concisely clear, has avoided the hidden fault point that is brought by unnecessary function design.
Summary of the invention
The objective of the invention is to propose a kind of method for monitoring of novel HVDC converter valve thyristor level operation conditions.
The present invention has designed a complete set of communication protocol, the coded system between HVDC converter valve thyristor level and the valve base electronic device, the statistical method of a kind of valve base electronic device to thyristor level running state information proposed, and a kind of fault message determination strategy that adopts for the information wrong report that prevents the gate pole unit.
The advantage of technical solution of the present invention is:
1, succinct gate pole unit and the coding stipulations between valve base electronic device
2, the monitoring method of reliable gate pole reported information.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 shows signal relation figure.
Fig. 2 shows the data flowchart between control board and the check-out console.
Embodiment
Thyristor method for monitoring of the present invention is: the serial of valve base electronic device receiving pole control system triggers coded command, and the triggering coding that transfers two pulses after the decoding to sends to the gate pole unit of each thyristor level.Each gate pole unit reports the running status repayment of current thyristor to encode to the check-out console that is positioned on the valve base electronic device of correspondence.Every corresponding 6 thyristor levels of check-out console on the valve base electronic device, microcontroller is opened up optical channel repayment detection window, FOP repayment detection window, is got energy good detection window according to triggering enable signal on the check-out console, and the pulse signal that occurs in corresponding detection window judges that promptly this repayment appears in the thyristor level.Concrete windowing method is:
1. being top with the 1st rising edge of a pulse that triggers dipulse, is end with the pulse trailing edge that stops to trigger, and detected 10uS pulse is considered as the FOP actuating signal between this window phase.
2. be top with the trailing edge that stops to trigger pulse, the optical channel that detects the TTM repayment in the window of tens microseconds of delaying time detects pulse.
3. the pulse of detected 10uS is that TTM gets enough the returning of energy beyond above two windows.
For avoiding the wrong report of gate pole unit, valve base electronic device adopts the method for timing counting to judge repayment, as accumulative total in 6 cycles same passage do not have repayment, then think this channel failure.Master control borad reads and gathers the thyristor operation information of whole valve tower by data/address bus.Signal relation is seen accompanying drawing 1.Master control borad adopts the multiplexing mode of bus to read the reporting information of check-out console.Detection system is divided into one group with per 3 check-out consoles, every group of corresponding 18 thyristor levels of check-out console, and 3 position datawires of public master control borad.5 bit address lines of the public master control borad of all check-out consoles are used as the foundation of channel selecting.Address wire adopts the displacement sign indicating number once to select 1 to 18 sense channel of every group of check-out console.This method makes master control borad can read at least 6 channel datas at a read data in the cycle.Shortened the cycle of Data Update so greatly.
The distribution of data wire sees Table 1.
| Data bit | Corresponding integrated circuit board |
| D0～D2 | Check-out console 1,2,3 |
| D3～D5 | Check-out console 4,5,6 |
| D6～D8 | Check-out console 7,8,9 |
| D9～D11 | Check-out console 10,11 |
| D12～D14 | Check-out |
The corresponding check-out console of table 1 data bit number
With optical channel testing process shown in Figure 2 is example, and master control borad is reported information and is stored in the specific memory space by the detection that the multiplexing mode of bus reads each passage in proper order.Then by therefrom extracting the optical channel data with logic.With following statement data by normally whether carrying out timing are added up.Do not judge that then this passage damages if receive the optical channel reward data within a certain period of time continuously.After this call communication program record is carried out in problem thyristor level position.Control again and report detected fault message when protection system was called out the VBE cycle of carrying out.
Invention has been described according to specific exemplary embodiment herein.It will be conspicuous carrying out suitable replacement to one skilled in the art or revise under not departing from the scope of the present invention.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present invention, scope of the present invention is by appended claim definition.
