| In recent years, China’s economy grows rapid. With therapid economy development and people’s living standardsincreasing, Society increasingly depends on energy, especiallyelectricity supply. The demand for electricity and its supplyreliability is growing. The safe and stable operation of the powersystem is directly related to the development of the nationaleconomy and people’s living.Regional power network is directly facing the user. Theeffect of the fault treatment is more controlled by the user’sattention. Relative to the main network, the structure of theregional power network is not so strong. With increasing systemcapacity, the grid runs more complex with more equipment andfarther transmission distance. At home and abroad in recentyears, there are many malignant grid fault. It means thattraditional processing strategy is gradually unable to adapt to thedevelopment of the grid. Therefore, according to thecharacteristics of regional power network, this paper analyzesthe basic elements of fault control from classification, prevention and positioning.Currently, smart devices have been widely applied in theregional power grid, such as automatic safety device, VARcompensation equipment, etc. This paper analyzes the positiveeffect of these intelligent devices to fault treatment, presents theproblems that need attention during devices operation, and striveto minimize the negative impact. Conclusions are demonstratedthrough examples.In addition, the gradual access of distributed power has alsobecome the trend of the development of the regional powernetwork. This paper analyzes the impact of distributedgeneration on stable operation, relay protection and faulttreatment. Conclusions are described by examples.In this paper, rail transportation is regarded as a part ofregional power network. A model is established for the treatmentand recovery of fault. This paper analyzes the advantages anddisadvantages of the fault positioning, presents a new matrixalgorithm suitable for rail transport grid fault and repair process.Subsequently, this paper presents the objectives and constraintsof fault recovery. It is regarded as a complex multi-objective,multi-constrained, discrete, non-linear mixed integercombinatorial optimization problem. It will be achieved through genetic algorithm.Finally, the paper concludes the full work and prospects thefurther exploration work of the research for fault control andtreatment strategy of regional power network. |
