Time threshold values and voltage switching threshold values and store in memory, voltage sample circuit enters according to default time delay threshold values
Row voltage data gathers, and the voltage data of collection is carried out by data processing module with the voltage switching threshold values preset
Relatively and according to comparative result control Intelligent capacitor action.
By interactive keyboard predeterminated voltage switching threshold values, time delay in dsp processor, threshold values and merit are set
Rate factor switching threshold values.Automatic reactive compensated controller uses voltage sampling circuit to access and current sampling circuit
Accessing, voltage segment then uses and is directly accessed, then by automatic reactive compensated controller built-in voltage sampling electricity
Road carries out being converted into voltage value, and carries out auto-reactive compensation throwing in the built-in default threshold values of dsp processor
The method cutting control performs cycle criterion, and chance judgement is given when needing to put into Intelligent capacitor, by DSP process
Device sends event and pushes to corresponding Intelligent capacitor through RS485 communication interface, and Intelligent capacitor accepts instruction and throws
Entering to run, dsp processor retransmits instruction simultaneously, sends Intelligent capacitor through GSM communication module and puts into
The SMS run；Current sampling circuit is by current transformer measured data transmission, through current sampling
Circuit amplifies and processes, and pushes data into dsp processor, by dsp processor through electric current, and power factor,
The COMPREHENSIVE CALCULATING such as idle, under determining idle deficient benefit state, performs the method that auto-reactive compensation switching controls
Cycle criterion, reaches condition, dsp processor send instruction and put into Intelligent capacitor.
As it is shown on figure 3, the method that auto-reactive compensation switching controls is as follows:
Criterion 1: threshold values 5 realities of calculating are set according to the time delay of dsp processor and adopt the speed of data, and depend on
Secondary carrying out 5 voltage data collections, the average calculating 5 magnitudes of voltage obtains meansigma methods for the first time, simultaneously
Carried out calculating and judging whether less than measured data for the first time by voltage switching threshold values × 1.05 of dsp processor
Meansigma methods；It is judged as that "No", actual measurement magnitude of voltage belong to normal range, exits reactive compensation switching and control to judge；
It is judged as that "Yes" then enters criterion 2；
Criterion 2: gather 5 voltage datas according to above method the most successively, calculate meansigma methods and with DSP at
Voltage switching threshold values × 1.02 of reason device carry out calculating contrast, if less than second time measured data meansigma methods；
It is judged as "No", second time measured data meansigma methods is judged with measured data meansigma methods contrast for the first time, as
Fruit is more than setting up, and actual measurement magnitude of voltage belongs to normal range, exits reactive compensation switching and controls to judge；Otherwise enter
Criterion 3；
Criterion 3: automatic reactive compensated controller sends the 1st group of Intelligent capacitor and puts into operation instruction, while the most successively
Gather 5 voltage datas, calculate meansigma methods, contrast with pre-set threshold value × 0.99, if be real less than third time
Survey statistical average；It is judged as "No", by average with second time measured data for third time measured data meansigma methods
Value contrast judges, if greater than establishment, and measured data meansigma methods and measured data meansigma methods for the first time for the third time
Carrying out contrast again to judge, for another example more than setting up, actual measurement magnitude of voltage belongs to normal range, and auto-reactive compensation controls
Device sends the 1st group of Intelligent capacitor instruction of excision, exits reactive compensation switching and controls to judge；Otherwise enter and sentence
According to 4；
Criterion 4: gather 5 voltage datas successively, calculate meansigma methods, contrast with pre-set threshold value × 0.97, be
No it is less than the 4th measured data meansigma methods；It is judged as "No", by the 4th measured data meansigma methods and the 3rd
The contrast of secondary measured data meansigma methods judges, if greater than being false, automatic reactive compensated controller sends the 2nd
Group intelligent capacitor puts into operation instruction；Otherwise enter criterion 5；
Criterion 5: gather 5 voltage datas successively, calculate meansigma methods, contrast with pre-set threshold value × 1.02, be
No it is less than the 5th measured data meansigma methods；It is judged as "No", by the 5th measured data meansigma methods and second
The contrast of secondary measured data meansigma methods judges, if greater than establishment, actual measurement magnitude of voltage belongs to normal range, automatic nothing
Merit compensating controller sends the 1st group and the 2nd group Intelligent capacitor instruction of excision, exits reactive compensation switching control
System judges；Otherwise perform cycle-criterion 4.
It is above control method when Intelligent capacitor occurs needing putting in factors of voltage, the switching of power factor (PF)
Control method is similar to it, namely carries out 5 voltages successively according to default time delay threshold values and current data is adopted
Collection, and calculate power factor (PF) respectively, finally calculate the meansigma methods of 5 power factor (PF) numerical value, then go and power
Factor switching threshold values compares judgement, and decision is to exit reactive compensation switching control process, or further
Judge.But when Intelligent capacitor occur needing to put in voltage and power factor (PF), with voltage sampling electricity simultaneously
The high priority data that drive test obtains.
