前言当前研制一种适合众多的60kV及以下电压等级的中、小供电网（包括用户电网）的具有可靠性高、实用先进、价格较低、使用方便，易于推广的工控微机集散式监控系统十分必要。下面就以已投入运行的某油田采油厂供电网微机实时监控系统工程为例，从可靠性、实用性和系统性三个
Preface The current development of a large number of 60kV and below the voltage level of small and medium power supply network (including the user grid) with high reliability, practical advanced, low price, easy to use, easy to popularize the IPC microprocessor control system is very necessary. The following has been put into operation in an oil field power supply network micro-computer real-time monitoring system engineering as an example, from the reliability, practicality and system of three
