| Nowadays,in order to realize the requirements of growing power consumption,it is necessary to enhance the capacity of domestic power grid power supply.Because of the power system must ensure the safety of the system power supply and provide customers with high quality electricity,it has become the urgent task to strengthen the construction of power distribution system.Therefore,the domestic,distribution system should be meet the power quality of power supply and distribation system based on a transformation plan of study to improve the ability of power system stable operation.In this paper,the overall operation characteristies of the power system in the northern part of a province are studied,and a typical substation in the area is taken the research object,First of all,combined with the research results and current situation of substation transformation at home and abroad,the necessity of typical substation transformation in this area is analyzed,the 110kV distribution area is completely reformed because there are many defects in the 110kV distribution equipment such as circuit breaker,isolation switch,transformer and so on,Based on the life cycle cost analysis model,the feasibility of the primary and secondary retrofit of 330kV and 110kV distribution equipment is studied,and the optimal retrofil scheme is setected.Finally,the feasibility of the reconstruction plan is demonstrated from four aspects:Environment,society,Finance and operation benefit.The typical substation of study has made a contribution to imroving the power supply capacity of the local power systen and ensuring stable power supply,and has a certain guiding signficance for the transformation of the same type substation in this area. |
