Relay protection is one of most important secondary device of electric system, its accuracy and reliability are directly connected to the safe operation of electric system, in real work, continuous expansion along with the construction of intelligent grid and the grid-connected and electrical network scale of generation of electricity by new energy, original check pattern no longer adapts to power network development under the new situation and meets informatization requirement, the management work of the specialty of relay protection is simultaneously such as equipment control, definite value management, setting value management, protection configuration waits work to be also badly in need of improving, mainly there is following problem in system at present, county adjusts and also rests on hand computation, the correctness of calculating can not obtain reliable guarantee, do not possess perfect relay protection management database, ground county adjusts the mutual of Equivalent Network, the cooperation of border definite value adopts man-machine interactively mode, cause Data Update not in time, and due to human negligence reason, cause makeing mistakes.
Under the overall background of building at intelligent grid, make full use of existing resource, the equipment that constructing function is perfect, easy to use, can be online relay and related data be carried out to verification, in order to improve reliability, economy and the management level of Operation of Electric Systems, become the new direction of electric power system dispatching development.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art; provide a kind of simple and practical; can detect relay data and on off state; and checking for sensitivity and the selectivity of relay protection, and the power grid integrated on-line testing device of energy detection of grid Power Flow Information.
The technical solution of the utility model is: a kind of power grid integrated on-line testing device; comprise protection definite value check module, intelligent scheduling module, maintenance information module; wherein: described protection definite value is checked module and is connected with intelligent scheduling module, maintenance information module; described intelligent scheduling module is connected with relay control module; described maintenance information module is connected with collecting device with Data Detection, and described protection definite value is checked module and is connected with printer, display, storer.
Described protection definite value is checked module and is connected with input equipment with pick-up unit, and described pick-up unit is arranged in electrical network.
Described protection definite value is checked module and is connected with at least one maintenance information module.
Between described maintenance information module and described Data Detection and collecting device, be provided with wireless receiving and emitter.
The beneficial effects of the utility model are:
1, the utility model overcomes the deficiencies in the prior art; provide a kind of simple and practical; can detect relay data and on off state; and energy detection of grid Power Flow Information; and check for sensitivity and the selectivity of relay protection; nearly standby sensitivity is not only protected in the verification of sensitivity, also protects standby sensitivity far away, and can point out not meet the protection definite value of sensitivity requirement.
2, between the utility model maintenance information module and described Data Detection and collecting device, be provided with wireless receiving and emitter, by wireless network, connect, can in time the data transmission detecting be gone out, the understanding of convenient operation person to relay situation.
3, the result of the utility model to online check; provide graphic interface to show that definite value meets situation; for the protection definite value not meeting the demands; output check result; for user, check; meanwhile, with text, provide the calculation original text of detailed check result, wherein comprise verification mode details, check the important intermediate information of calculating and do not meet claimed detailed reason etc.
4, the utility model provides the check result file of XML form, mainly comprises protection branch road, existing definite value, meets situation and do not meet the details that definite value is relevant, meanwhile, also can generate a detailed check process computation book, and add a cover timestamp.
accompanying drawing explanation:
Fig. 1 is power grid integrated on-line testing apparatus structure block diagram.
embodiment:
Embodiment: referring to Fig. 1.
Power grid integrated on-line testing device: comprise protection definite value check module, intelligent scheduling module, maintenance information module; it is characterized in that: protection definite value is checked module and is connected with intelligent scheduling module, maintenance information module; intelligent scheduling module is connected with relay control module; maintenance information module is connected with collecting device with Data Detection, and protection definite value is checked module and is connected with printer, display, storer.
Protection definite value is checked module and is connected with input equipment with pick-up unit, and pick-up unit is arranged in electrical network.
Protection definite value is checked module and is connected with at least one maintenance information module.
Between maintenance information module and Data Detection and collecting device, be provided with wireless receiving and emitter.
During use, operating personnel use input equipment to carry out the input of reference data and parameter, pick-up unit arrives protection fixed value checking module by the data upload detecting, for checking the whole network definite value, according to sensitivity principle and principle of selectivity, process, every corresponding interval of principle meeting, be more than or equal to or be less than or equal to, judge whether definite value meets this principle and only need judge that existing definite value is whether in the definite value interval of this principle, for principle of selectivity, may exist a part of adjacent legs definite value is met to selectivity, another part branch road does not meet optionally situation, can automatically generate standby definite value and check calculation original text, define which protection definite value and there is no sensitivity, which protection definite value does not have selectivity, finally provide graphic interface to show that definite value meets situation, for the protection definite value not meeting the demands, output check result, for user, check, simultaneously, the calculation original text of detailed check result is provided with text, wherein comprise verification mode details, check the important intermediate information of calculating and do not meet claimed detailed reason etc., also can generate a detailed check process computation book, and add a cover timestamp.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
