Integrated automation monitoring system in the application of 220kV substation Yan Yan1, Xinghua Ma2 Feifei Ji3 12 College of Sciences, Hebei United University, Tangshan, Hebei, China 3 College of Mining Engineering, Hebei United University, Tangshan, Hebei, China yanjxky@126.com Keywords: Substation, monitoring system, integrated automation control system Abstract.
This itself is a enormous waste of human and material resources, when debugging the same work twice must be done twice, but also is unlikely to ensure both identical, and meanwhile bring contradictory to the protection.
Conclusion In view of the substation automation system in the next stage is also a lack of a unified national standard, This requires in the actual operation constantly summarize experience, and find the regularity, Do not follow the beaten track, And because under the circumstances, we should follow the spirit of science to build the substation automation system To ensure the power safety and economy, high-quality operation.

Developing new cathode materials with good performance at intermediate temperature is the key to low down the operating temperature[1,2].
Perovskite oxides, La1-xSrxCo1-yFeyO3-δ systems, belong to this family of mixed ionic-electronic conductors, and have attracted interest with potential applications as oxygen separation membrane or as cathode material for SOFC[4,5,6].

The castable refractories discussed here are that using alumina cement as the bonding agent [2] The ultrasonic velocity of the shear and longitudinal waves in an isotropic material, linearly elastic bulk solid are related to the density and the elastic moduli [3].
The accurate measurement of the velocity of this signal can be effectively used to evaluate many parameters of the material and to detect flaws in test pieces.

Ferromanganese and ferrosilicon are charged after slagging off in the furnace and before the iron is melted, with the aims of increasing the amount of manganese in melted iron, initial inoculation, hardness of the materials and graphite form.
Either too high or too low contents of Mn and S will change the metallographic structure and mechanical property of the materials, as a result of which the requirements of customers cannot be met.
But a decrease of contents in C and Si will induce the production of chill spots [7] on D type graphite,which has to be avoided; meanwhile thinning of casting walls demands that the material improve its strength on one hand; On the other hand, chilling tendency caused by increase of cooling velocity also has to be avoided.
