Problems existing substation automation substation automation stations in the plant design and configuration

Zhu indistinct substation automation in our more than ten years of development, becoming more perfect and mature , improve the power grid has become a safe and reliable operation of the mandatory measures , widely used in the country . But substation automation applications still exist some problems. This article from the substation automation plant stand design and configuration , information processing and  mcb circuit breaker  the application of these angles . Problems existing substation automation substation automation stations in the plant design and configuration , information processing primarily in the following three questions. Traditional analog  power transformers  collection method is to a high voltage device information through the transformer 5 is converted to a voltage signal and current signal IA knife , the corresponding  Circuit breaker  the second cable protection and control device, the device and then through the respective small transformer to convert it again to implement it collected . And because the protection and control devices on the technical requirements of the current transformer is not the same , you need to install the transformer , respectively . Since the nodes in the grid substation , is the source of a variety of electrical quantities collected , so there are often multiple sets of substation systems and equipment , such as mechanized from the system , fault recorder , PMIJ more.
