摘 要：The integrated development of information and communication technologies has a positive effect on the management level and safe production of power companies. It can change the situation of weak technical services and single management mode， and achieve healthy and stable development of enterprises. In order to accelerate the process of convergence of information and communication technologies， power companies must continue to innovate in maintenance and operation， so that they can better play a role in grid production and operation， and help enterprises create a first-class power grid.

　　1.Introduction
　　Effective and timely transmission of power information by power companies is a prerequisite for the application and development of power communication technologies. Integrating power communication technology and power information technology can truly create a scientific， reasonable， safe and effective power information system to help power companies automatically control power. The information management work has improved the efficiency of power companies.
　　2.Significance of the integration and development of power grid information and communication technology
　　Under the premise of digitalization in the world， information and communication technologies are gradually becoming an important role in power management， marketing， providing a safe and efficient production for the power industry[1]. It is of great significance to abandon the traditional model of the development of information and communication， and integrate the symbiotic resource environment and development pattern， laying a foundation for the healthy long-term development of power companies[2].
　　3.Key elements of the integration and development of grid information and communication technology
　　3.1Power transmission network communication technology
　　At present， the communication network of power companies basically uses optical fiber as the transmission trunk， and some large power companies are forming an optical transmission network to replace the traditional communication network. The optical transport network is divided into a management plane， a control plane and a transport plane， which realizes automatic management， connection and configuration of the optical transport network.
　　3.2Power exchange network communication technology
　　Flattening， converging and IP are the main features of the switching network. The switching network is the core technology of NGN. The integration and integration of the network can fully meet the needs of end users for multimedia and diversified services， and fully realize the integration of video， data and voice.
