Description
Technical field
The present invention relates to electric system, different saving energy and decreasing loss technology priority level analyses of particularly a kind of town and country power distribution network and selecting method.
Background technology
Along with the propelling of intelligent grid construction and the primary energy that reduces day by day, the matter of utmost importance that the power distribution network saving energy and decreasing loss has become electric system to face.Saving energy and decreasing loss has become electric system to need the problem of solution badly.A lot of scholars are devoted to the saving energy and decreasing loss Study on Technology.Find that under study for action different saving energy and decreasing loss renovation techniques exists to intersect and conflicts in actual implementation process.For example, when a heavily loaded transformer being carried out the saving energy and decreasing loss transformation, owing to the reason that causes the transformer heavy duty may be because overload, also may be because transformer reactive-load compensation deficiency, if adopt reactive-load compensation to make transformer no longer heavily loaded, then do not need transformer is done transformation again, thereby saved substantial contribution, a kind of method of the optimization of capital that Here it is.Use substation transformer economical operation system simultaneously, also can solve the heavily loaded problem of transformer, but therefore its economic effect for the solution of transformation heavy duty problem, should at first consider reactive power compensation technology not as the reactive-load compensation transformation.
In this external real work, Utilities Electric Co. is when carrying out the power distribution network technological transformation, often lay particular stress on a certain local link, can't plan as a whole the optimization of comprehensive realization power distribution network technological transformation, and each technological transformation mode is lacked the research that becomes more meticulous, the selection of each modification measures is not had the planning of comprehensive pool.
Summary of the invention
Defective at above-mentioned art methods and existence thereof, purpose of the present invention aims to provide a kind of when being used for town and country power distribution network saving energy and decreasing losses and transforming, the interactional analytical approach of different saving energy and decreasing loss technology, and the prioritization method of selecting the saving energy and decreasing loss technology for distinct device for use.Based on the thought of prioritization, to different classes of element and scrap build the time, realize each technology improvement method is formulated its corresponding priority level order.Transform element select work the time at first consider the technological transformation model that priority is higher, descend successively, thereby solved the conflicting problem of technological transformation, realized the analysis that becomes more meticulous of modification measures, for the optimization of fund for technical innovation provides the foundation.Simultaneously, this also is the mode that each technology model is realized by software.
The foundation of this invention is at first energy-conservation impairment technology to be classified according to its technical characterstic, mainly comprises 5 classes: (1) measuring apparatus transformation, harmonic wave control; (2) substation transformer reactive-load compensation, circuit reactive-load compensation, application idle work optimization configuration software; (3) use substation transformer economical operation system; (4) improving distribution transformer, distribution line transformation, low-voltage circuit transformation, application single phase distribution transformer, application circuit pressure regulator; (5) electrical network boosting and transformation, high voltage are introduced load center.According to the technical characterstic of each classification, comprise its realization approach then, analyze its mutual influence, and it is carried out prioritization, thereby when different equipment is transformed, according to the priority of various renovation techniques, the corresponding transformation technology of selecting reduces the saving energy and decreasing loss cost.
For realizing that the technical scheme that the different saving energy and decreasing loss technology of above-mentioned town and country power distribution network adopt may further comprise the steps:
1) with the classification of modification measures
In order to realize the prioritization of modification measures, at first each renovation technique is sorted out, will adopt different processing modes to different technology models.Actual research work according to various places is summed up, and analyzes the enforcement of each renovation technique and relation each other thereof, and all technical modification measures are classified.
The first kind: measuring apparatus transformation, harmonic wave control.
Second class: substation transformer reactive-load compensation, circuit reactive-load compensation, application idle work optimization configuration software.
The 3rd class: use substation transformer economical operation system.
The 4th class: improving distribution transformer, distribution line transformation, low-voltage circuit transformation, application single phase distribution transformer, application circuit pressure regulator.
The 5th class: electrical network boosting and transformation, high voltage are introduced load center.
2) all kinds of modification measures are carried out prioritization
1. priority one: measuring apparatus transformation, harmonic wave control
The priority of measuring apparatus transformation and harmonic wave control is come most significant digit, be not these two Measures of technical to the damage work of falling of Utilities Electric Co. is most important, but because the decision of the singularity of its implementation.
There are different separately characteristics in these two Measures of technical, measuring apparatus is transformed multi-point and wide-ranging, harmonic wave control is primarily aimed at the user that some harmonic waves do not satisfy national standard, the technology model of these two modification measures carries out accurate analog computation and all has difficulties on software, therefore, can carry out manual intervention to it, earlier these two required inputs of modification measures be calculated, and in total transformation funds, deduct.The fund that surplus capital is used as other modification measures.
Manual intervention judgement (user decides in its sole discretion) is reserved a part of special fund and is carried out Measuring Reformation (pressing measuring apparatus and low-temperature measurement device in comprising) specially.The suggestion which measuring apparatus technology model provides should transform, how to transform, how guides user carries out this transformation.
According to GB GB/T14549-93 " quality of power supply utility network harmonic wave ", do not satisfy the power consumer of national standard for harmonic wave, Utilities Electric Co. must force it to carry out harmonic wave control.So this falls the damage measure is to fall to decrease one that modification scheme must comprise.Prioritization scheme is a target with the economy under the prerequisite that satisfies reliability and security, and therefore, the realization of harmonic wave control can judge whether this area needs to carry out harmonic wave control by user's manual intervention.
2. priority two: substation transformer reactive-load compensation, circuit reactive-load compensation, application idle work optimization configuration software.
In electric system, the defective and heavily loaded problem of a lot of voltages all causes owing to idle a large amount of transmission, if carried out rational reactive-load compensation, has transformed with regard to not needing to carry out element again.So the priority of the correlation model that reactive-load compensation is transformed should be higher than other element renovation techniques.
Substation transformer reactive-load compensation simultaneously, circuit reactive-load compensation, these three kinds of technology of application idle work optimization configuration software also are conflicting, if adopted the idle work optimization configuration software, then can directly use the analog result of software; If do not adopt the idle work optimization configuration software, then can realize idle optimization by substation transformer reactive-load compensation and circuit reactive-load compensation.
Because substation transformer reactive-load compensation, circuit reactive-load compensation, these three kinds of technology of application idle work optimization configuration software are conflicted mutually, therefore need carry out prioritization to these three kinds of technology, and are specific as follows:
Local priority one: use the reasonable disposition that the idle work optimization configuration software carries out reactive-load compensation.
Local priority two: substation transformer reactive power compensation technology
Local priority three: circuit reactive power compensation technology
The prioritization foundation:
Use the reasonable disposition that the idle work optimization configuration software carries out reactive-load compensation.Invest and fall the damage benefit and all can obtain by the Technological Economy model.If without the idle work optimization configuration software, idle configuration is optimized to network by substation transformer reactive-load compensation and circuit reactive-load compensation model Expert Rules in suggestion.According to relevant rules and guide rule, the reactive power source of electric system and load or burden without work, all should adopt branch (voltage) floor on the peak or during low ebb and divide () district principle in a basic balance to be configured and to move, and should have var regulating power and overhaul reserve flexibly.Simultaneously, principle according to idle in-situ balancing, should be in the configuration of reactive power compensator in the power distribution network based on the reactive-load compensation of substation transformer, also exist the built on stilts basic routing line of 10kV of power factor problem can take into account the reactive-load compensation of line road after the substation transformer reactive-load compensation.
3. priority level three: use substation transformer economical operation system
By the substation transformer economical operation, may solve the heavily loaded problem of part substation transformer, therefore, use substation transformer economical operation system priority and be higher than improving distribution transformer, and for the solution of heavily loaded problem, at first consider it is reactive-load compensation, the priority of therefore using substation transformer economical operation system is the 3rd.
4. priority level four: improving distribution transformer, distribution line transformation, low-voltage circuit transformation, application single phase distribution transformer, application circuit pressure regulator
Because such Technology Need transforms element, comprehensively its economic benefit and improvement cost, it is the 4th that damage measure priority falls in such technology, need enter the optimization flow process, satisfies the optimization that realizes economy under the prerequisite of security and reliability.
5. priority level five: electrical network boosting and transformation, high voltage are introduced load center
Adopt high voltage power transmission can reduce line loss, but need carry out boosting and transformation to existing line, its improvement cost height.Therefore the priority level of such technology is minimum.
When the power distribution network element being carried out the saving energy and decreasing loss transformation, need select the element of needs transformation according to expert's principle.Below be detailed introduction:
Expert's principle can be divided into mandatory criterion and non-imposed criterion two big classes by its character.The element that mandatory criterion is picked out requires mandatory the transformation, the optional transformation of the element that non-imposed criterion is picked out.
In criterion was implemented, mandatory criterion and non-imposed criterion will judge to the element in the electrical network simultaneously that element gathers element after selecting and finishing, and sorts out division by the character of its transformation.Specific to expert's principle of each model,, then implement according to the sequencing of model defined if the sequencing that criterion is implemented is stipulated.(annotate: these sequencings are not the orderings of carrying out according to mandatory or non-imposed character, but formulate according to the logicality that decision element is selected)
According to the difference of select element transformation character, select corresponding optimization flow process for use.
According to the research to the electrical network boosting and transformation, its transformation is on a grand scale, and transformation funds is huge, so the user need be in conjunction with local conditions, and fully feasibility study, and then make a strategic decision and whether adopt this modification scheme.The electrical network boosting and transformation model that the present invention sets up only provides the suggestion what situation is fit to carry out the electrical network boosting and transformation, and investment, benefit are provided some empirical datas, and is only for reference.
Simultaneously, it mainly is because newly-built transformer station of needs can not satisfy situation such as burden requirement time of transformer station that high voltage is introduced load center, its transformation scale is also very big, the fund of transforming is also huger, the user should fully prove according to the actual conditions of locality, and whether decision-making needs to adopt this measure then.The high voltage that the present invention sets up is introduced the load center model and is only provided this measure of suggestion employing under certain conditions, and its investment, benefit are provided empirical data.
Therefore, these two kinds of technology reforming schemes of electrical network boosting and transformation and high voltage introducing load center will not enter and fall the transformation and optimization scheme of decreasing.Can be used as an independent functional module uses for the user.The method that provides according to model, and in conjunction with local conditions, provide the user and whether be fit to carry out the electrical network boosting and transformation, high voltage is introduced the suggestion of load center.
The different saving energy and decreasing loss technology priority of town and country of the present invention power distribution network level is analyzed and selecting method, in the engineered process of the town and country of reality power distribution network saving energy and decreasing loss, the one, can avoid falling the repeated use of damage technology, the 2nd, can realize adopting minimum cost to realize the saving energy and decreasing loss transformation.For example, when to one because OL heavily loaded transformer carries out saving energy and decreasing loss when transforming, if adopt reactive-load compensation can make transformer no longer heavily loaded, then can avoid adopting mode that it is transformed to the transformer transformation, the former cost is greatly about several thousand yuan to several ten thousand yuan, and the latter's cost often surpasses 50,000 yuan, therefore as can be seen, adopt priority analysis, and select for use the saving energy and decreasing loss technology effectively to reduce cost.
