Description
Technical field
The utility model belongs to electrical network field, is related to the risk assessment of the area power grid method of operation and aid decision-making system.
Background technology
China is with the development of power grid, and the safety challenge of power grid is increasing, and a large amount of electric power scholars make much thus
Contribution.The main contents of Study of Risk Evaluation Analysis for Power System can be divided into component-level risk assessment and system-level risk assessment.
Component-level risk assessment：Electric system is by a large amount of generator, overhead transmission line, cable, transformer, open circuit
The compositions such as device, disconnecting switch and reactive-load compensation equipment.Element stoppage in transit is the basic reason of thrashing, and system risk assessment is first
First to determine the outage model of element.Component failure is divided into independent and two classes of correlation and stops transport, and stops transport per a kind of can further press again
Pattern is segmented.In most cases, recoverable forced outage is only included in, also planned outage is simulated sometimes.It passes
Ageing failure is not considered in the risk assessment of system, and considers that the model of component ageing failure conditions is more reasonable in practice, is obtained
Result more gear to actual circumstances.What risk assessment considered first is the risk assessment of element, but with previous component reliability research
Unlike, element risk assessment will not only carry out the foundation of mathematical model, and also need to develop real-time monitoring system, system
The cost of new equipment is purchased after counting primary equipment failure, and carries out some measurement experiments.
System-level risk assessment：The property analyzed according to system mode the research of system-level security risk assessment at this stage
Qualitative classification can substantially divide into two aspects of static security risk-assessment and dynamic security risk-assessment.
Whether static security risk assessment characterization system can fully meet the workload demand of user and the constraints of system operation,
Therefore static security risk-assessment relates only to the limit of system, carries out the abundance analysis of system without requiring
Dynamic and transient analysis process；Dynamic secure estimation analysis then shows responding ability of the system to dynamic and transient disturbance, therefore
The disturbance occurred in system and its consequence are evaluated.Usual dynamic secure estimation will carry out transient state, voltage stability point
Analysis.With the development of system, collapse of voltage and cascading failure accident gradually protrude, and the analysis of both of these problems are had become quiet
State safety analysis important component.At present, the most of risk assessment technologies used in engineer application belong to static security
Property analysis scope, risk indicator be also mostly abundance size index rather than totality risk indicator.
Safe operation of electric network risk assessment, domestic correlative study substantially experienced three phases：Certainty evaluation stage,
Probability assessment stage and Risk Assessment Stage.Certainty assessment usually only considers that the accident of most serious, the knot of assessment occur for system
Fruit is overly conservative, and the cost paid is higher, uneconomical.Probability assessment generally only considers the size of risk probability of happening but does not consider
The consequence order of severity that risk occurs, and risk assessment combines risk accidents probability of happening and risk schedule severity, wind
Product of the danger value for the two, assessment result can reflect the risk level residing for system.
At present, based on the research of risk assessment also in the elementary step, the practice being usually taken is：In certain constraint
Under the conditions of, to respectively drafting pre-program, to carry out single or more comprehensive economic index or single operation of power networks, management related
Index assessed.These assessments are all to have carried out relevant assessment with regard to some aspect of power grid or certain several aspect, and
Major part is assessed with qualitatively language, lacks certain theoretical foundation, and assessment result is excessively subjective and coarse so that comments
Estimate result to have a greatly reduced quality.
