摘 要
由于全球资源不断减少，环境压力增大，普通用户对电能稳定性和实用性的要求逐渐提高，变电所也由于时代的发展而发展以微处理器为中心的智能化自动装置被广泛使用。
随着数字变电所成为电力网的物理基础，正在快速发展。IEC61850标准的颁布、实施，为数字电站的数据集成奠定了基础。随着社会的发展，传统的变电站已发展为数字变电站。对数字变电所的基础和发展情况进行概述后，简述现阶段的数字变电所的最新技术。这包括非常规互感器、智能电路断路器、防止数字变电所通信网和干扰的措施等。然后将结合抚州地区的实例对数字化变电站在抚州地区的应用做具体介绍。
最后是未来展望，数字化变电站现在还在发展中，仍然有很多技术难关没有攻克，有很多难点还需要进一步研究。

Abstract
Due to the decrease of global resources and the increase of environmental pressure, the requirements of ordinary users for the stability and practicability of electric energy are gradually improved. With the development of the times, the intelligent automatic device with microprocessor as the center is widely used.
With digital substation becoming the physical basis of power network, it is developing rapidly. The promulgation and implementation of IEC61850 standard has laid a foundation for data integration of digital power station. With the development of society, traditional substation has developed into digital substation. After summarizing the foundation and development of digital substation, the latest technology of digital substation at present is introduced. This includes unconventional transformer, intelligent circuit breaker, measures to prevent communication network and interference of digital substation. Then the application of digital substation in Fuzhou area will be introduced with the example of Fuzhou area.
Finally, the future prospects, digital substation is still in development, there are still many technical difficulties have not been overcome, there are many difficulties need to be further studied.
Key words: Fuzhou，Digital substation，Secondary system，IEC61850 protocol
