智能双微机自动准同期装置的设计

ＳＪ—１２Ｃ型双微机自动准同期装置是在ＳＪ—１２Ａ（Ｂ）基础上结合实际运行需要而开发的新一代更新换代产品。它含有两块独立的ＣＰＵ板，一块完成同期点预报及发电机电压、频率的调节功能，另一块完成闭锁功能。该装置保留了原同期装置的优点，增加了许多新的功能，如汉字液晶显示，无需改变硬件配置即可满足多达１６个不同类型的同期点的自动准同期，友好的人机界面，相位补偿及线性调节等，从而大大提高了装置的总体性能。文中主要介绍了ＳＪ—１２Ｃ型双微机自动准同期装置的设计原理、结构配置及特点。

THE DESIGN OF INTELLIGENT DUAL-MICROCOMPUTER AUTOMATIC SYNCHRONIZATION DEVICE

SJ-12C intelligent dual-microcomputer automatic synchronization device is a new product which is based on the old type SJ-12A(B) and can meet the requirements of any kinds of power system synchronization practice.Besides the advantages of old type SJ-12A(B),SJ-12C has many new functions.It's made up of two independent CPUs.One CPU accomplishes the forecast of synchronization and the regulation of generator's voltage and frequency,and the other performs the locking function.Meanwhile,a set of friendly designed MMI,the function of phase compensation and linear adjustment etc.,make SJ-12C easier to use and maintain.In this paper,the design principle,structure and the characteristics of SJ-12C are introduced.
