自备电厂自动准同期并列装置的研制

The automatic throwing switch device for backup power plant

为了解决自备电厂的并网问题，提高用电可靠性，依照并网基本要求，研制出一种数字式自动并列装置，该装置以８０３１单片机为核心，通过Ａ／Ｄ转换采集数据，单片机处理数据，Ｄ／Ａ转换控制发电机，达到自动调节并网．在实验中实现了发电机电压的自动调节与并网，也可用于一般电厂．

In order to make the generator of backup power plant get into the circuit and improve its reliality,on account of the need for automatic switch, a numerical automatic switch into the circuit installation is introduced. It uses the 8031 single chip computer as its core,the A/D convertor to sample data, the 8031 to process the data,and the D/A convertor to output the data to control the generator.
