Abstract
The utility model discloses an electric energy quality analysis system, which comprises a system data storage device, an electric energy data acquisition instrument and a protocol converter, wherein the system data storage device is connected with the protocol converter, the protocol converter and the electric energy acquisition instrument are connected with an input end of a data interface, an output end of the data interface is connected with an electric energy quality data processor, and the electric energy quality data processor is connected with a display module. The electric energy quality analysis system can analyze impacts exerted to the electric energy quality of a power grid to be accessed to by an enterprise planning to transfer, and can rectify and reform the power grid to be accessed to according to the analysis results, thereby ensuring the electric energy quality to be qualified, guaranteeing the safety of the power grid, and improving the economic benefits of electricity utilization at the same time.
Description
Technical field
The utility model relates to a kind of analytic system, particularly a kind of analytic system for the quality of power supply.
Background technology
Along with the propelling of industry transfer, part medium and small sized enterprises change economic Backward area over to and produce, and generally a little less than this type of area power grid relative thin, the load scale is less, may cause this area's electrical network quality of power supply to descend after enterprise's access network system.Existing Analysis System for Power Quality can be analyzed the existing electrical network quality of power supply, but can't analyze the impact that the electrical network quality of power supply causes the enterprise that shifts or build that is being planned, and can't play in advance preventive effect.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of planning transfer enterprise that analyzes on the system of the impact of the electrical network quality of power supply to be accessed.
The technical scheme that the utility model solution prior art is taked is:
A kind of Analysis System for Power Quality, comprise system data storage, electrical energy data acquiring instrument and protocol converter, described system data storage is connected with protocol converter, described protocol converter is connected with the input end of data-interface with the electrical energy data acquiring instrument and is connected, the output terminal of described data-interface is connected with the power quality data processor, and the power quality data processor also is connected with display module.
The beneficial effects of the utility model: electric network data and transformer station's related data of access are stored in the system data reservoir now with enterprise, the electrical energy data acquiring instrument gathers electrical network energy data to be accessed, the data of system data reservoir after protocol converter conversion and the data communication device of electrical energy data acquiring instrument collection cross data-interface and be transferred to the power quality data processor and carry out Treatment Analysis, and on display module the display analysis result.The technician can do corresponding rectification to electrical network to be accessed according to analysis result, has ensured the security of electrical network, has improved simultaneously the economic benefit of electricity consumption, has guaranteed good social benefit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is operational flowchart of the present utility model.
Embodiment
With reference to Fig. 1, a kind of Analysis System for Power Quality, comprise that system data storage 1, electrical energy data acquiring instrument 2 be connected described system data storage 1 and be connected with protocol converter 3 with protocol converter, described protocol converter 3 is connected with the electrical energy data acquiring instrument and is connected with the input end of data-interface 4 respectively, the output terminal of described data-interface 4 is connected with power quality data processor 5, and power quality data processor 5 also is connected with display module 6.Wherein, the data of system data storage 1 storage comprise Substation Bus Arrangement figure and the method for operation that grid side and subscriber station join; The substation project operation year that grid side and subscriber station join and the load data in planning year; The project operation year of customer substation access electrical network point and the minimum capacity of short circuit in planning year; Customer substation main wiring diagram and the method for operation.The data that electrical energy data acquiring instrument 2 gathers comprise load equipment capacity at different levels, load utilization factor, load simultaneity factor, load current, power factor and electric motor starting electric current multiple; Load side filtering at different levels and compensation equipment capacity; Direct current, frequency conversion equipment capacity, rectification commutation mode and equipment individual harmonic current.The data that power quality data processor 5 is processed comprise electric system points of common connection supply voltage voltage fluctuation and flicker; Each harmonic injects the harmonic current of points of common connection; The total percent harmonic distortion of voltage, each harmonic voltage containing ratio and cause the imbalance of three-phase voltage degree.
With reference to Fig. 2, the enterprise that planning is moved, the electric network data that enterprise now can be accessed and transformer station's related data are stored in the system data reservoir 1, in addition, electrical energy data acquiring instrument 2 gathers the energy data of electrical network to be accessed, the data communication device of system data reservoir 1 and the collection of electrical energy data acquiring instrument is crossed data-interface 4 and is transferred to power quality data processor 5 and carries out analyzing and processing, result is presented on the display module 6, the technician can judge whether electric energy is qualified according to result, if qualified, then finish; If defective, then electrical network to be accessed is carried out the analysis of causes, propose corresponding solution and according to scheme electrical network is rectified and improved.After the rectification, electrical energy data acquiring instrument 2 continues to gather the electrical network energy data, and processes to power quality data processor 5 with the data transmission of system data reservoir 1, judges according to the result that display module 6 shows whether electric energy is qualified, if qualified, then finish; If defective, the technician continues electrical network to be accessed is rectified and improved, so circulation until the quality of power supply qualified till.
The above is the better embodiment of the utility model, and it does not consist of the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
