| Current our country economy is in a good period of high-speed development, very urgent demand for electricity, meanwhile our country electric power industry system is in the key period of reform, electric power security is particularly important; It is not only an important condition whether reforms smoothly carries on, it is an important sign of examination reform, regardless of the power system reform, power production inner inherent characteristics and objective law will not change, will not weaken the security of the power supply enterprise responsibility, in the key period of power system reform measure whether a power supply enterprise safety management can be in the first place, the key is to look for "safety responsibility is more important than mount tai" measures to carry out the deep is not deep, thin is not fine, yan is lax, strength big, the power industry is a high technical requirements, wide range and complex system, and the system engineering of high maintenance costs, in the process of economic development plays a very important role, it is the important foundation of the national economy. Therefore, there is a risk of electric power industry is very high.In order to can let the local power supply enterprise to improve their ability to cope with sudden accident processing, at the same time guarantee the healthy development of the power supply industry. This article from the local power supply enterprise’s safety management present situation analysis, through the grid structure, technology, accidents, and run to establish evaluation index system of power grid security early warning, such as power grid safety state evaluation model by the improved analytic hierarchy process and multi-objective linear weighting function to build, to the local power supply enterprise safety management in detail on the early warning signal system, at last, through the empirical verification, the result shows that the establishment of the early warning mechanism is has a certain practical value and theoretical significance. |
