Abstract
The invention relates to a distributed power fault recording system for an intelligent power grid. The distributed power fault recording system comprises intelligent collectors, main controllers and a background control system. The intelligent collectors and the main controllers are connected; and the main controllers are connected with the background control system by a wireless network. The intelligent collectors are used for detecting electric parameters and determining whether fault recording is carried out based on the detected electric parameters. The main controllers are used for collecting quantity values of the intelligent collectors; when the intelligent collectors are in fault recording states, the background control system sends synchronous fault recording starting commands to other main controllers; and other main controllers control all intelligent collectors at a lower level to start fault recording. The background control system is used for carrying out management and overall planning on the fault recording data of all main controllers. Therefore, the reliable guarantee can be provided for security of the power system.

Accompanying drawing explanation
Fig. 1 is the system schematic of the present invention；
Fig. 2 is multichannel analog signals acquisition system structural representation in the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments be merely to illustrate the present invention and
It is not used in restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, people in the art
The present invention can be made various changes or modifications by member, and these equivalent form of values fall within the application appended claims equally and limited
Scope.
Embodiments of the present invention relate to a kind of intelligent grid distributed power fault recording system, as it is shown in figure 1, include intelligence
Energy harvester, master controller and background control system；Described intelligent collector is connected with master controller, and described master controller leads to
Cross wireless network to be connected with background control system；Described intelligent collector is used for detecting electric parameter, and according to the electric parameter of detection
Judge whether to failure wave-recording；Described master controller is for the collection capacity of described intelligent collector, when intelligent collector is in
During failure wave-recording state, send synchronization failure wave-recording by background control system to other master controller and start order, other
Its lower floor of main controller controls all intelligent collector startup separator record ripple；Described background control system is for all masters
The fault recorder data of controller is managed and plans as a whole.
As in figure 2 it is shown, described intelligent collector include being sequentially connected conditioning filter unit, sampling holder, multiple signals
Selector and analog-digital converter, described conditioning filter unit for being amplified filtering to multichannel input signal；Described sampling is protected
Holder keeps for the filtered signal of amplification is carried out sampling；Described multiple signals selector is used for carrying out multy-way switching and makes
Multiple signals become one-channel signal；Described analog-digital converter is for being converted to digital signal by the analogue signal of single channel.After completing
The digital signal of each passage is saved in the data storage area of inside, detects various electric parameter whether within normal range, enter
Row fault detect.
Described master controller uses embedded core board, carries linux system, and intelligent collector passes through PCI adapter and master
Controller is connected, and carries out data transmission.Communicated by wireless network between master controller and background control system.Master control
Device processed receives the order of back-stage management machine, passes a parameter to intelligent collector；After failure wave-recording starts, master controller reads
The collection capacity of intelligent collector data storage area, and it is sent to background control system by wireless network；If in system other
Intelligent collector breaks down and records ripple startup, and the master controller on its upper strata can be by background control system other master in network
Controller transmission synchronizes failure wave-recording and starts order, after other master controller receives synchronization failure wave-recording startup order, starts
The failure wave-recording of all intelligent collectors of its lower floor；Back-stage management machine the recorder data of all master controllers is managed and
Plan as a whole.When carrying out failure wave-recording, intelligent collector provides startup time and the initial address of corresponding data of record ripple, other
The time labelling of data point is according to being the interval time of each two point (1/ sample rate).Intelligent collector passes through GPS synchronizing signal
When carrying out system school, it is ensured that time synchronized is a range of error the least.
In order to find the operation troubles in power system in time, and recorder data can be transmitted rapidly to the main control on upper strata
Device.Therefore use parallel data computing and data transmission, i.e. data processing unit and interface unit is designed as relatively independent two
Individual functional module.Data processing unit reads data, and completes waveform fault startup judgement, the record wave number that interface unit preserves
Read according to for master controller.
It is seen that, the present invention can provide for power system security and ensure there is good practicality reliably, can be existing
Transform on some equipment, tradition electrical network is intelligent, by the transmission of wireless network, intelligent grid electricity can be found in time
Operation troubles in Force system, and inform background control system in time.
