Description
Technical field
The present invention relates to electric power system data management, particularly relate to low-voltage power supply reliability based on Multi-data Source Mining essence
Really analyze method and system.
Background technology
Power supply reliability refers to the electric power system ability to user's continued power, and power failure not only can cause huge to country
Big economic loss, and the life of the people and the stable of society can be affected.Along with economic develops rapidly and people's lives water
Flat improves constantly, and user is more and more higher to the requirement of power supply reliability, and power supply reliability is substantially needing of power consumer
Ask, Ye Shi power supply enterprise self-growth basic goal.
At present, the power system power supply reliability assessment work of China primarily focuses on middle pressure (10kV) and system above,
Be usually and add up as ultimate unit using 10kV distribution transforming, and the power supply reliability statistics of developed country states such as () Great Britain and Americas be with
Low-voltage customer (380/220V) is as elementary statistics unit.If power supply reliability only count on Middle Voltage be cannot reflect vast
The actual power reliability of low-voltage customer, it is therefore necessary to the statistical work of power supply reliability is extended to low pressure.
Obtain actual demand to solve users, a set of low-voltage distribution system Reliability Evaluation index body need to be proposed
System, and provide low-voltage power supply reliability Accurate Analysis method, thus the power supply that auxiliary power supply department grasps low-pressure system comprehensively can
By property level, it is achieved customer power supply reliability management truly is to family, and finds the weak ring affecting power supply reliability
Joint, improves user power utilization satisfaction and power supply enterprise's good service level.
It is 2 points that the statistics of power supply reliability does not extend intos the main cause of low pressure:

Loss bigger, therefore power supply enterprise more payes attention to ensureing the power supply reliability of high pressure system；
2) automaticity of medium voltage network is higher, collects power failure data relatively low pressure and more accurately facilitates, and desired data amount is also
Less, and low-voltage customer has a very wide distribution, the equipment automatization level of informatization is relatively low, and the collection of data needs people mostly with statistics
Work completes and there is the problem of mass data disappearance, and general area is all difficult to count on accurate low-voltage power supply reliability.
Traditional distribution network reliability evaluation method includes analytic method and Monte Carlo simulation approach.Both approaches is the most all
Need to set up reliability model of unit, then carry out three steps: condition selecting, state estimation, index calculate.Analytic method is root
According to the random parameter of element, set up the reliability model of system, obtained the indices of power supply reliability by numerical computations.Often
See analytic method include minimal path shot, Minimal Cut Set, Interval evaluation method, network morals education, state space method, fault mode with
Consequences analysis method etc..There is feature with a high credibility, but due to computationally intensive, retrained by system scale, be poorly suitable for
Complicated large scale system.Monte Carlo simulation approach initially sets up the probabilistic model of element and system, and the parameter of model is reliable
Property index, is then provided probability distribution and the statistical nature of reliability index, finally gives reliability and refer to by sampling approach
Target approximation.The method is applicable to various network, is not limited by network size, but this have time-consuming, precision is low etc. lacks
Point, foundation as bad in the partition model of low-pressure system, sample size be bad to be determined, the precision of assessment result cannot ensure.
Above-mentioned traditional method is required for setting up the reliability model of element, but low-voltage distribution system has multi-point and wide-ranging
