Embodiment
As described in background, existing SCADA system is limited by fore device, collection capacity only comprises basic electric weight, voltage, the data such as electric current, cannot be to more truly reflecting the three-phase first-harmonic of circuit operation conditions, frequency, the data such as fundamental positive sequence phasor gather, therefore, when there is significant trouble in the users such as high ferro, the data of true reflection circuit operation conditions cannot be provided, and, due to the reason such as database processing is limited in one's ability, cause existing SCADA system can only carry out according to the fixed cycle of 5 minutes collection and the storage of data, therefore, its data that provide may not be the True Data of time of failure point yet.
Why existing SCADA system, sample according to the cycle of 5 minutes for the load data of the responsible consumers such as high ferro, and the disposal ability of database is limited is an important reason.For responsible consumers such as high ferro, civil aviatons, accident often occurs between the least bit, traditional periodic sampling can not provide the slight change of complete circuit perfect information data, so real-time sampling is following trend, and real-time sampling is compared with periodic sampling, data acquisition scale is by the difference that presents hundreds of times, because real-time sampling has, collection period is short, data volume is large, the features such as data redundancy is large, therefore the magnanimity real-time sampling data storage that, how to realize the responsible consumers such as high ferro is also the absorbed emphasis of electric power system.
That is to say, SCADA system of the prior art can not, to more truly reflecting that the data such as three-phase first-harmonic, frequency, fundamental positive sequence phasor of circuit operation conditions carry out Real-time Collection, be unfavorable for judgement and the processing of fault.
Based on this, the invention provides a kind of user power utilization data real-time monitoring system, the problems referred to above that exist to overcome prior art, comprising:
Synchronous phasor measuring device, for the real time data on synchronous acquisition electricity grid substation side line road, described real time data comprises three-phase first-harmonic, frequency and fundamental positive sequence phasor;
Fault wave recording device, breaks down and locates the dynamic real time data of circuit for record when breaking down.
User power utilization data real-time monitoring system provided by the invention, by the real time data on synchronous phasor measuring device synchronous acquisition electricity grid substation side line road, realization is to the real-time estimate of the running status of electrical network and monitoring, and, by fault wave recording device, when breaking down, record the dynamic real time data of the place's circuit that breaks down, can effectively make up and break down front and back synchronous phasor measuring device disappearance or occur abnormal data, thereby guarantee the integrality of data.
Hence one can see that, user power utilization data real-time monitoring system provided by the present invention, by being combined with of synchronous phasor measuring device and fault wave recording device, collection user's that can be complete real time data, the running status of supervisory user circuit, thus produce and the safe and stable operation of the responsible consumer such as high ferro provides solid guarantee for electric power safety.
Be more than core concept of the present invention, for above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention be described in detail.
