2) on the basis of main wiring diagram, typical platform district distribution wiring diagram, payload, character and feature, the power consumption of studying each region in time and Seasonal fluctuation etc., the theory wire loss model of foundation based on multiple computing method, and stores synchronized is in described terminating machine;
Wherein, distribution wiring diagram comprises network structure, line length, wire diameter and the power supply number of phases;
The foundation of theory wire loss model is the core of this line loss analysis system, and it,, for the various parameters that may obtain, transfers respectively the COMPREHENSIVE CALCULATING that different models carry out line loss per unit;
Line loss model what realize software application is MATLAB model emulation software, Model Calculating Method mainly contains following several:
The first is to take sample rate current as model parameter, the mean value of calculating sampling electric current and root-mean-square value, utilize both equivalent relations to carry out line loss calculating, it is equivalent to straight line by current capacity curve, thereby overcomes reometer sampled data instantaneity, the accurate low shortcoming of rank.This model is mainly applicable to computer board district electric current branch line complicated situation, according to main line and a line current, the feature of successively decreasing according to ' bamboo joint type ' rule, suppose following condition, the one, a line length of all specifications is identical, entrance line number is equal, and load is evenly distributed, and entrance line distributes identical on branch line; The 2nd, all electrical node voltage equates; The 3rd, all entrance lines are equal in length, it is identical to load; The 4th, branch line is evenly distributed on main line, and this is a kind of more novel line loss computation model;
The second is loss of voltage model, utilizes the ratio of power loss rate and loss of voltage rate to carry out rough calculation to low-voltage network theory wire loss, and according to setting loss formula, can derive power attenuation rate is COS with the ratio of voltage loss rate
2φ
-1, wherein, φ is power-factor angle for sampling electrical network, because this model computation process is simple, calculate the data that need few, so can be set at parameter acquisition less, in the situation that needs to respond fast, call, but its error calculated is bigger than normal, is only applicable to estimation;
The third model is that line resistance loss and the loss of transformer copper loss are replaced with the fixedly substitutional resistance loss of hypothesis, and the information that it need to be collected is few, and irrelevant with electric network composition.Due to rural area, platform district has close load nature of electricity consumed, for the rural power grids with the less present situation of reactive power compensation capacity, adopt single equivalent model can make to calculate more for convenience, but for platform district, city, between load, load nature of electricity consumed difference is larger, equivalent model also needs to carry out repeatedly trend by the set method of operation of the original substitutional resistance of electrical network and hypothesis and calculates, and cooperation calculates line loss electric weight from meritorious, the idle and voltage readings of circuit head end measuring apparatus collection.It is also the simulation curves that can use MATLAB that trend is calculated, and transfers equilibrator curve, load curve and power curve and carries out, and checkout result repeatedly, consist of the experiment form of statistical study;
Except above method, can also be according to making computation model when the actual conditions of foreground partition, for example introduce genetic algorithm or artificial neural network algorithm is set up model of mind, this is a kind of fuzzy control method.In system, after repetition test, determine the most applicable discrete domain when foreground partition, to realize the optimum control that is applicable to Self-variation.
3) by described data acquisition module, realize the data acquisition of low-tension transformer and/or user side, through data transmission module, be uploaded to core processing module formation and record form, and continuous data is plotted to data and curves, show in real time;
Data acquisition end can, by wired or wireless form, be pooled to system terminal computing machine by Information Monitoring.Information Monitoring comprises output voltage values, current value, performance number, power factor, charge value, harmonic wave, frequency of power cut, reactive-load compensation etc.;
When the theory wire loss that carries out platform district calculates, the workload of collecting raw data is very large.Therefore line loss is calculated and is not only selected suitable computation model, guarantees the accuracy of result of calculation, also will consider accurately to gather and calculate service data data and electrical equipment parameter data;
The Yi Moutai district transformer station collection situation of a day is example: gather with the service data data of calculating and comprise: the record of power, electric current, voltage, power factor and the whole day delivery of input during running on time, output in transformer station, circuit, measuring apparatus etc. 0～24 hour; The positive point load that representative is in a few days recorded is chosen in utilization, supposes that one hour internal loading fixes, the daily load curve of drawing; The period substation transformer secondary summary table calculating copy total electric weight of seeing electric weight and transformer station's Source of Gateway Meter; Each actual motion hourage of operation vigour part etc. of being correlated with in the period calculating;
Electrical equipment parameter data mainly comprises the rating data of the controller switching equipment such as substation transformer, reactor, capacitor in the specifications and models of wire that electrical network is used and conductor length and electrical network and the nameplate data etc. moved.
4) according on existing power supply data basis, image data ，Tai district, make A+E, and by comparing calculation, draw the input data that line loss model needs;
The input data of line loss model mainly refer to all kinds of factors of Low-voltage Line Loss fluctuation, and it not only comprises multiple inherent data, such as conductor resistance, transformer model etc., also comprises working voltage, running current, power factor etc.The former can be by calling the corresponding original nameplate parameter of terminating machine database lookup, and latter need to be weighted, is averaged, triangular transformation etc. method is calculated, and calculates and realizes by the function transaction module of MATLAB;
Access time each user's power electric meter of segment record reading, ask in platform district the delivery of the calculating line segment of dividing, computational scheme substitutional resistance; The existing power supply data in Dui Tai district are made on the basis of A+E, choose representational circuit and representational time period and measure daily load change curve, in the hope of being averaged electric current, load curve characteristic coefficient etc.
5) bring input data into line loss model and calculate, and comprehensively analyze the unbalanced various situations of three-phase load, relatively theory wire loss and practical line loss, show that line loss parameter is line loss per unit;
The calculating of theory wire loss model for be single parameter, must analyze through comprehensive, especially consider that the low voltage electric network in the unbalanced situation ，Dang Tai of three-phase load district is when three-phase load non-equilibrium state, out-of-balance current will be in alternate generation, the generation of out-of-balance current not only increases the loss in phase line, also caused the loss on the neutral line, thereby increased total line loss, if three-phrase burden balance, vector is zero so, does not have neutral line loss;
Suppose that certain three-phase four-wire system circuit total load electric current is 3I, three-phase current unbalance, one is 2I mutually, and another two-phase is respectively 0.5I, and neutral current is 1.5I, power attenuation is compared during with three-phase equilibrium, loss has increased by 1.25 times, and three-phase imbalance can make line loss obviously increase as can be seen here, supposes that all load is by a power supply mutually, power attenuation has increased by 5 times during than complete equipilibrium, so adjust three-phrase burden balance, should become the first-selection of line loss model outside calculating and falls damage measure.
6) contrast affects the parameter that line loss per unit is larger, finds out parameter place node, and real-time update terminating machine station table information is also shown information device for addressing by station node is carried out to addressing location;
