Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.A kind of power transformation direct current integrated monitoring and early warning method of the present invention is applicable to monitoring management in transforming plant DC integration power-supply system.
Figure 1 shows that the overview flow chart according to embodiment of the present invention.Data acquisition uses monitoring modular to gather the data that substation equipment produces, and usage data storehouse stores, and the data of database purchase can be called; Historical data Trend Algorithm calls the analog data stored in data and calculates, and obtains analog data tendency chart; Accidental data parser is called the state quantity data change stored in data and is analyzed, and carries out corresponding fault pre-alarming according to comparing result; Redundant data parser is called the associated data stored in data and is carried out association judgement, judges whether system exists fault according to result of determination; Data Self-healing Algorithm calls the invalid data stored in data, and associates alternate process accordingly to invalid data; Figure list processing is warned abnormal data for using warning reports.
Figure 2 shows that the historical data trend analysis figure according to embodiment of the present invention.System according to the time interval of setting, reads corresponding data from database from database, generates tendency chart, can find out the variation tendency of data intuitively, and when data variation is larger, analyzes reason, prevents the fault that may occur, is convenient to safeguard.System mainly will carry out trending analysis to important analog datas such as battery voltage, charging current, monomer battery voltage, internal resistance of single cell, cell temperature, floating current, branch insulation resistance
Figure 3 shows that the accidental data analysis chart according to embodiment of the present invention.Mainly change comparative analysis is carried out to state quantity data.When system normal operation input, each quantity of state keeps normal operating condition constant, and system automatically can form quantity of state throwing and move back table.When quantity of state is undergone mutation, can change according to this fault carried out early warning and may occur.Feeder switch states as all in system, part is in input state, part is in stand-by state, when system is normally run, these switch states keep initial condition constant, if situation as shown in the figure appears on off state, quantity of state changes, early warning load equipment may break down or think misoperation thus, and judges system failure reason according to concrete quantity of state change.
Figure 4 shows that the redundant data analysis chart according to embodiment of the present invention; The data of system acquisition, have very major part to be mutually related relation, some is equal, and some is mutual exclusion, so-called redundant data that Here it is.Under system normal operating condition, these data should meet relation that is equal or mutual exclusion, if do not meet, then and illustrative system fault.As when system cloud gray model is normal, in error allowed band, close female voltage=accumulator battery voltage=220V.If display result is different, then illustrative system operation exception, can according in error allowed band, redundant data be related to that this is to judge system operation situation.
Figure 5 shows that the data self-healing figure according to embodiment of the present invention.When module communication failure, when there is no data, can replace according to equivalence (incidence relation is equal) data the data lost efficacy, realize simple data self-healing.As when wherein any one data failure is 0 for the female voltage of conjunction, accumulator battery voltage, all can replace by another data, because data meet close female this relation of voltage=accumulator battery voltage.As shown in the figure, when the female voltage inefficacy of conjunction is 0, available battery group voltage is replaced and is closed female voltage, realizes the simple self-healing of data with this.
The above, just preferred embodiment of the present invention, the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.In protection scope of the present invention, its technical scheme and/or execution mode can have various different modifications and variations.
