A set of fuzzy technology theoretical origin based on photovoltaic power station operational system
Fuzzy theory (Fuzzy Theory) refers to have used the basic conception or continuous membership function of fuzzy set
It is theoretical.It can be categorized as fuzzy mathematics, fuzzy system, uncertain and information, fuzzy decision, fuzzy logic and artificial intelligence this
Five branches, they are not completely self-contained, there is closely contact between them.For example, fuzzy control will use it is fuzzy
Concept in mathematics and fuzzy logic.From from the viewpoint of practical application, the application of fuzzy theory is largely focused on fuzzy system
On system, it is particularly concentrated in fuzzy control.
Fuzzy theory is in photovoltaic power station operational system with main in following several respects：
Fuzzy set
The concept fuzzy set of fuzzy set is theoretical, also referred to as fuzzy set theory, or is simply referred as fuzzy set.This method handle
Object to be investigated and reflect that its fuzzy concept, as certain fuzzy set, sets up appropriate membership function, by fuzzy
The relevant computing and conversion of set, are analyzed to fuzzy object.Fuzzy set theory is based on fuzzy mathematics, and research is relevant non-
Accurate phenomenon.In objective world, many bloomings being this or that largely are there are.
Utilization of the fuzzy set on Database.
Fuzzy set database is set up, power station status information, operation maintenance personnel status information, power failure problem, failure is former
Cause, failure measure, instrument, material, effect etc. all as fuzzy object, these objects are stored on backstage with database form,
So that application program is called by fuzzy logic, fuzzy control scheduling theory.
Fuzzy logic
Fuzzy logic refer to the uncertain concept for imitating human brain judge, reasoned thinking mode, for unknown-model or can not
The descriptive system of determination, and strong nonlinearity, large time delay control object, made inferences using fuzzy set and fuzzy rule,
The transitional boundary of expression or Qualitative Knowledge experience, simulate human brain mode, carry out fuzzy comprehensive estimation, and it is difficult that reasoning solves conventional method
In the regular pattern composite fuzzy message problem for tackling.The unsharp Qualitative Knowledge of the expressive boundary of fuzzy logic and experience, it by
In membership function concept, fuzzy set is distinguished, process fuzzy relation, simulate human brain code fo practice type reasoning, solved because " in row
The logic of rule " breaks a variety of uncertain problems for lacking generation.
Fuzzy logic is used in the statistical analysis of problem power station.
It refers to relatively pinpointing the problems by the service data of multiple equipment that landscape blur compares analysis, such as by two
Or the daily generation of many faciation same model inverters carries out contrast discovery, the generated energy if one or several inverter is total
It is lower than group's inverter fuzzy value (fuzzy value is according to actual conditions dynamic change), then we just can consider that generated energy is low
This or several inverter efficiencies are low or suspected malfunctions, may also be used for judging the quality of inverter whereby.
Longitudinal direction is fuzzy, and to compare analysis refer to point to treat desorption device, one section of comparing of the service data fuzzy set in period of vertical analysis
To pinpoint the problems, the daily generation and PR values (power station generating efficiency) for contrasting inverter to be analyzed carry out contrast discovery, if this
The generated energy and PR values of platform inverter start generated energy and PR values in certain day slowly to be reduced by a fuzzy value (fuzzy value is according to reality
Situation dynamic change) glide, then we just can consider this inverter suspected malfunctions, may also be used for judging inversion whereby
The quality of device.
Fuzzy control
Fuzzy control is using the basic thought and theoretical control method of fuzzy mathematics.In traditional control field,
The whether accurate of control system dynamic mode is the good and bad main key of influence control, and the dynamic information of system is more detailed, then
The purpose of precise control can more be reached.However, for complicated system, because variable is too many, it tends to be difficult to correct description system
The dynamic of system, then just simplifies system dynamic using various methods, to reach the purpose of control but preferable not to the utmost.Change speech
It, traditional control theory has powerful control ability for clear and definite system, but for excessively complexity or is difficult to accurately retouch
The system stated, then seem helpless.Therefore just attempt processing these control problems with fuzzy mathematics.
Fuzzy control automatically generates utilization in O＆M scheme.
Normal data is set up with current domestic line brand fault of converter solution, when new event occurs in inverter
Barrier, by fuzzy logic technology, to phenomenon of the failure data fuzzy matching, finds the interim fuzzy set of failure basic reason, then right
The interim fuzzy set of basic reason for analyzing has the root cause database to carry out mould by fuzzy learning technology to data place again
Paste compares searching rule to find out the fuzzy interim collection of all relative solutions, and last fuzzy statistics solution out is fuzzy
Temporary validity carries out weight Fuzzy Synthetic Evaluation analysis, so that system automatically generates O＆M scheme, when O＆M confirms new life
Into O＆M scheme it is effective after phenomenon of the failure, basic reason, contact measure are added into original database mould with fuzzy set data mode
Paste set, by accumulating over a long period for long-term, gradually forms O＆M large database concept.
Field Using Fuzzy Comprehensive Assessment
Field Using Fuzzy Comprehensive Assessment is a kind of integrated evaluating method based on fuzzy mathematics.The comprehensive evaluation is according to fuzzy number
Qualitative evaluation is converted into quantitative assessment by the topology degree that is subordinate to learned, i.e., with fuzzy mathematics to the things that is restricted by many factors or
Object makes an evaluation for totality.It has result clear, the characteristics of systematicness is strong, can preferably solve it is fuzzy, be difficult to
The problem of quantization, is adapted to the solution of various uncertain problems.
Utilization of the Field Using Fuzzy Comprehensive Assessment in job order distribution.
There is new failure power station again all during outer O＆M in operation maintenance personnel, and failure power station can be automatic automatically according to fuzzy
The means such as logic, fuzzy control automatically generate job order, factor of evaluation mainly comprising operation maintenance personnel O＆M task, O＆M circuit,
Operation and maintenance tools, O＆M material, operation maintenance personnel ability, O＆M duration etc., average value and weight are set to each factor of evaluation, are passed through
Field Using Fuzzy Comprehensive Assessment is evaluated one by one to all factors of evaluation, finally makes comprehensive evaluation value, and system will newly clap work automatically
Singly distribute to comprehensive evaluation value highest operation maintenance personnel.
Fuzzy decision
Fuzzy decision refers to the mathematical theory and method that decision-making is carried out under fuzzy enviroment.Conventional fuzzy Decision Making Method has
Fuzzy Sorting, Fuzzy Seeking and fuzzy game etc..
Fuzzy Sorting refer to research policymaker how to determine various decision schemes under fuzzy enviroment between good and bad order.
Fuzzy Seeking is showed after determining scheme collection and various object functions and restrictive condition, seeks optimal case and has become one
Individual optimization problem.
