摘要:随着电力网络智能化程度的提高，智能企业变配电的自动化系统提上了议事日程。计算机技术在变配电自动化中的应用，使得变配电自动化程度大大提高。企业变配电自动化程度的提高可以提高供配电的可靠性与安全性，方便了企业工作人员的工作。
本文以工厂供配电自动化监控系统为研究对象，采用VB技术、单片机信号采集技术，设计了一个监控平台，实现了监控系统的基本要求，能够监控工厂供配电网络的运行情况，实现用户管理、数据显示、报警系统等功能。
工厂供配电监控系统的主要设计内容是：
(1) 系统主接线。清晰明了地显示系统的变压器、电容器、馈线的一些技术数据。
(2) 数据显示。显示供配电网的断路器状态，用电设备的状态。
(3) 报警系统。当变配电网参数发生较大变化及主变发生异常时，产生报警信息，提示用户。
(4) 用户管理。可以实现用户密码登录。用户的权限受到严格的管理。
该监控系统直观、简便地实现了工厂监控系统的自动化管理，满足了系统安全性、实时性的要求。应用前景广阔。

Abstract:As the electric power network intelligent degree rise, intelligence enterprise change of power distribution automation system has been put on the agenda. Computer technology in the change of the application of the power distribution automation, make change distribution automation degree is greatly increased.The improvement in the level of power automation can improve power supply reliability and security and makes life convenient.
This design in the factory for distribution automation control system as the research object, using VB technology and single-chip microcomputer signal collection technology, design of a monitoring system, realize the basic requirements of the monitoring system, can monitor factories for distribution network movement situation, realize user management, data shows, alarm system, and other functions.
The main contents of the power automatic monitoring system are as follows:
(1) The main network system can display some technical data clearly of transformers, capacitors, feeders, and the control cabinets in the system.
(2) The automatic monitoring system can display Circuit breaker, Electric equipment state and other data of the electricity network.
(3) When the electricity network parameters are changed greatly and when the
transformers are abnormal the alarm information is generated to tell the users.
(4) In the user management module you are allowed to add users, change your password and permission. The user’s permission is strictly managed.
The monitoring system is intuitive and easily automate the management of the plant monitoring system to meet the requirements of the system security, real-time，and has a bright future.
