Abstract
The invention discloses a query method of a state query system for a control and protection mainframe of a direct-current converter station. The method includes the specific steps: inputting information into a configuration file; reading the configuration file; connecting the system with the mainframe; judging whether the system can be normally connected with the mainframe or not; parsing and logically summarizing state data; completing query in case of abnormal display; and completing query in case of normal display. The method has the advantages that the method aims at overcoming the current situations of large workload, time and labor consumption and proneness to errors in converter station MACH2 mainframe state query, the state data, which are queried by a maintainer for hundreds of times and taking tens of minutes, of the control and protection mainframe of the direct-current converter station, can be obtained instantaneously, working efficiency is improved effectively, misoperation can be avoided, recovery time of the control and protection mainframe of the direct-current converter station after fault is saved greatly, and operation and maintenance of the converter station are facilitated.
Description
Technical field
The invention belongs to the D.C. high voltage transmission control field, refer to particularly a kind of querying method of DC converter station control protected host status inquiry system.
Background technology
What the control protection system of most domestic DC converter station adopted is the MACH2 technology; MACH2 control protection system nucleus equipment then is the control protected host; it is the large mesencephalic centre of control protection system, mainly is responsible for data and processes, operates control, system protection etc.At host maintenance, disappear lack and restart after, for prevent main frame recover normal operation after mistake send out trip signal, the O﹠M personnel must check one by one whether each Tripping matrix exists outlet signal, main frame self-test signal whether to have unusually in the main frame.Generally, every control protected host has up to a hundred variablees the mode with debug to check in HIDRAW software.For the control protected host of abnormal, if tuning error etc. occurs in the abnormal conditions, outlet signal check omission or the query script that occur to recover as early as possible, all will directly threaten the safe and stable operation of Bipolar DC power system.
Summary of the invention
The objective of the invention is to provide in order to overcome above-mentioned deficiency a kind of querying method of DC converter station control protected host status inquiry system.
For achieving the above object, the technical solution used in the present invention is:
A kind of querying method of DC converter station control protected host status inquiry system, concrete steps are:
Step 1: the configuration file of the described Host Status automated inquiry system of host information typing of the DC converter station control protected host that will need to inquire about;
Step 2: described Host Status automated inquiry system reads described configuration file, and host information in the configuration file is written into the main interface of Host Status automated inquiry system;
Step 3: the Host Status automated inquiry system connects DC converter station control protected host by NET DDE agreement;
Step 4: judge that can the Host Status automated inquiry system normally be connected to DC converter station control protected host, if then turn next step, otherwise the prompting of the main interface display connection failure of Host Status automated inquiry system and return step 3;
Step 5: the Host Status automated inquiry system reads the status data of DC converter station control protected host, and status data is resolved and logic gathers by described configuration file, judge namely whether DC converter station control protected host status data comprises protection action and alerting signal, as comprise and turn step 6, then turn step 7 as not comprising;
Step 6: DC converter station control protected host status data comprises protection action and alerting signal, illustrate that DC converter station control protected host exists unusual, the Host Status automated inquiry system is finished query script by the abnormal prompt of main interface display DC converter station control protected host and unusual status data;
Step 7: DC converter station control protected host status data does not comprise protection action and alerting signal; illustrate that DC converter station control protected host is normal; the Host Status automated inquiry system is finished query script by the normal status data of main interface display DC converter station control protected host.
The invention has the beneficial effects as follows for the workload that occurs in the current conversion station MACH2 Host Status inquiry work large; the present situation that wastes time and energy and easily make mistakes; utilizing this method that the operating maintenance personnel need to be spent dozens of minutes carries out the DC converter stations control protected host status datas of inquiries up to a hundred time and obtains in moment; use this method with the Effective Raise work efficiency; and avoid the possibility of maloperation; greatly save the release time after DC converter station is controlled the protected host fault, make things convenient for the work of current conversion station operation and maintenance.
Description of drawings
Fig. 1 is the querying method process flow diagram of DC converter station control protected host status inquiry system of the present invention.
Embodiment
Further specify the present invention below in conjunction with drawings and Examples.
Embodiment: the present invention is that a kind of querying method of DC converter station control protected host status inquiry system may further comprise the steps:
Step 1: the host information typing Host Status automated inquiry system configuration file of the DC converter station control protected host that will need to inquire about;
Step 2: the Host Status automated inquiry system reads configuration file, and host information in the configuration file is written into the main interface of Host Status automated inquiry system;
Step 3: the Host Status automated inquiry system connects DC converter station control protected host by NET DDE agreement;
Step 4: judge that can the Host Status automated inquiry system normally be connected to DC converter station control protected host, if then turn next step, otherwise the prompting of the main interface display connection failure of Host Status automated inquiry system and return step 3;
Step 5: the Host Status automated inquiry system reads the status data of DC converter station control protected host, and status data is resolved and logic gathers by described configuration file, the outlet signal of judging Tripping matrix still has " 1 " for " 0 " entirely, turn step 6 if any " 1 ", for " 0 " then turns step 7(" 1 " expression unusually, " 0 " expression is normal as complete);
Step 6: the outlet signal of DC converter station control protected host Tripping matrix has " 1 ", illustrate that DC converter station control protected host exists unusual, the Host Status automated inquiry system has " 1 " and red alarm by the outlet signal of main interface display Tripping matrix, finishes query script;
Step 7: the outlet signal of DC converter station control protected host Tripping matrix is " 0 " entirely; illustrate that DC converter station control protected host is normal; the Host Status automated inquiry system is " 0 " and green normal signal by the outlet signal of main interface display Tripping matrix entirely, finishes query script.
In step 1; host information comprises the DC converter station control protected host title that need to overhaul and the data of operating maintenance needs, and the data that operating maintenance needs comprise the outlet signal of the interior Tripping matrix of DC converter station control protected host and main frame self-test signal etc.
In step 5, the Host Status automated inquiry system reads the status data of DC converter station control protected host, and status data is resolved and logic gathers, and judges that the outlet signal of Tripping matrix still has " 1 " for " 0 " entirely.
In step 6, the outlet signal of Tripping matrix has " non-zero ", and the Host Status automated inquiry system is " 1 " by its result of main interface display, and shows red alarm, illustrates that breaking down of DC converter station control protected host is unusual, finishes query script;
