本文提出将水电站机组自动准同期并列这个独特的重要环节与机组生产过程微机控制同时考虑加以解决(选用AppleⅡ微机控制系统由另文说明)。由于同期并列的特殊性,必须采取特殊的办法来实现。重要内容之一是设计一个专用同期接口电路板,并选用若干集成电路块,将机组同期并列需要检测的参数如发电机电压、频率、电力系统电压、频率、判断事故的若干参数、允许进入同期过程的条件等,分别输入AppleⅡ机,经数据处理逻辑判断后发出各种调节命令、同期合闸命令或者事故停机命令。研究结果证明,能将Z80CPU特有的功能很强的定时/计数接口电路芯片CTC成功地与AppleⅡ微机6502CPU连接使用,不但解决了同期测频的问题,而且扩大了AppleⅡ微机的硬件资源,增强了AppleⅡ微机功能。另一个重要内容是用BASIC语言进行同期程序设计,功能很强、简明易写、极为方便。同期系统还充分发挥AppleⅡ微机各种外设的功能,如存储同期程序、显示同期过程状态事故情况等。众所周知,与电力系统同期并列是水电
In this paper, we propose to consider the unique combination of automatic quasi-contemporaneous generation of hydropower units and the microcomputer control of the production process of the generating units (using the Apple II microcomputer control system described separately). Due to the particularity of the same period, special measures must be taken to realize it. One of the important contents is to design a dedicated synchronous interface circuit board and select several integrated circuit blocks. The parameters of the generator to be tested simultaneously, such as generator voltage and frequency, power system voltage and frequency, and parameters for judging the accident, are allowed to enter the same period Process conditions, were imported Apple II machine, the data processing logic to judge after the issue of a variety of adjustment orders, the same closing command or accident shutdown command. The research results prove that the CTC, which is a very powerful timer / counter interface circuit chip that can be used in the Z80CPU, can be connected with the Apple II microcomputer 6502CPU. It not only solves the problem of frequency measurement in the same period, but also expands the hardware resources of the Apple II microcomputer and enhances the Apple II Microcomputer function. Another important content is to use BASIC language for simultaneous programming, powerful, easy to write, easy. Over the same period the system also give full play to the functions of various peripherals Apple Ⅱ microcomputer, such as the storage of simultaneous procedures, indicating the same period the status of the process of accident and so on. As we all know, parallel with the power system is hydropower
