摘要
本文介绍了研制的以１６位单片微机为核心的ＵＦＶ－２型低频低压自动减载与解列装置。该装置能够反映系统内功率缺额的大小，快速切除相应数量的用户负荷，在联络断开时能按地区电网功率缺额的数值联切足够的负荷，以确保电网的安全运行。该装置具有自动识别、躲开短路故障功能，其完善的自检、自试和多种闭锁措施保护了装置的安全性与可靠性。
in this paper a new UFV-2 type fre-quency and voltage control relay for power system e-mergency state based on a 16-bit single chip microcom-puter is introduced. It can shed load as fast as the dropof the frequency and the voltage and the amount of theload shedding can keep pace with the development ofthe power shortage. It can split the power system andshed load in the isolated system where the active pow-er source is not enough.The relay will not operateduring simple short circuit fault. It has perfect contin-uous self-monitoring,self texting and many otherfunctions to ensure the security and reliability.
