The Analysis On The Operation Of The Power Grid In Huhhot

A series of power failures have happened worldwide in recent years, and many accidents ware voltage collapses caused by the mis operations of relay protection and auto mechanisms for the changed operational conditions,leading to large-scale blackout.Learning from the lessons of power failures at home and broad,it is necessary to pay much attention to the enlarged electricity grid failure, which might cause the security and stability problems influenced by voltage collapse,owing to weak power source in the load center,the unreasonable configuration and setting of protection relays,inadequate voltage supporting ability and so on.It has important social and economical signification to study the operation condition of power system.First, the paper analyses the current situation and existent problems in operation in Huhhot power grid, and puts forward the measures of improvement.Using the short-circuit current calculation under the various methods,it checks the short-circuit level of equipments in the power grid. Second, with the calculations of analysis, the paper proposes some corresponding measures against the existent problems in operation, and makes corresponding adjustments for the operation,which makes the operation and coordination of the power grid more reasonable.In the last part, it analyses the present loads and forecasts the future load, puts forward the some appropriate advices on the development of the power grid during the "twelfth Five-Year "Plans.It offers technical support and scientific instruction on the operation of the power grid in Huhhot.
