Aiming at the current status of power enterprise without effective information integration platform,the integration methods for electric power utility s real-time information is analyzed and the integration information technology is introduced based on the CIM(common information model)/CIS(component interface specification).

The IEC(International Electrotechnical Com-mission) 61970 CIS(Component Interface Specification) is the practical way of public data exchange.

This paper mainly discusses the method of using extensible markup language(XML)Web Services,which is recommended by IEC 61970,to implement the component interface specification(CIS)in IEC 61970.

As the core of IEC 61970, the component interface specification (CIS) including the common information model (CIM) extensible markup language (XML) I/O, generic data access (GDA) and high-speed data acquisition (HSDA), is implemented in this paper.

This system is formed by a global control AVC of the power grid and multi-regional hierarchy control AVC, which can satisfy the requirements of dispatching, and realize AVC interconnection of global control AVC of the power grid and hierarchy control AVC from CIS interface.

This paper presents the architecture of a network intrusion detection system based on common standard, describes the intrusion specification language through the instance, and analyze the inside communication mechanism and procedure interface standard.
