DS-10恒定导前时间型准同期装置是浙江省机械科学研究所专为小水电及其出口需要而研制的新型准同期装置。已于1984年1月通过鉴定。它主要适用于500千瓦及以下低压水轮发电机组并入电网或机组间的自动并列。它的研制成功,有助于小水电的推广使用,也有利于小水电的出口配套。本成果具有电压差、频率差、恒定导前相角自动闭锁等功能,设有连续可调的恒定导前时间环节,能准确可靠地自动发出导前时间恒定不变的并列脉冲,能与国产低压发 DS-10 constant pre-time type quasi-contemporaneous device is a new quasi-contemporaneous device developed by Zhejiang Institute of Machinery Science for small hydropower and its export needs. In January 1984 passed the appraisal. It is mainly suitable for automatic parallel combination of low-voltage hydro-generator sets of 500 kilowatts and below into the grid or between units. Its successful development helps to promote the use of small hydropower, but also conducive to the export of small hydropower facilities. The results of a voltage difference, frequency difference, constant lead phase angle automatic locking and other functions, with continuously adjustable constant lead time link can be accurately and reliably automatically send the same lead time constant pulse, with domestic Low pressure hair
