为了提高水轮发电机组自动化水平,推广使用先进技术,新丰江四号机采用了全晶体管弱电逻辑控制装置,与DT-100电调组成的机组自动化装置。逻辑装置是广州电器科学研究所设计制造的:DT-100电调是东方电机厂配套产品。自动装置曾在水下电站与威井电站试用,并经过较长期的运行考验。经过改进,在大型水轮机组首次采用。自动控制的范围为:(1)开机准同期并列;(2)停机;(3)运行改压气调相;(4)机组故障及
In order to improve the automation level of hydro-generating units and popularize the use of advanced technology, Xinfengjiang No.4 machine adopts a full-transistor weak logic control device and a unit automation device composed of DT-100 ESC. Logical device is designed and manufactured by Guangzhou Institute of Electrical Science and Technology: DT-100 ESC is an accessory product of Dongfang Electrical Machinery Factory. Automatic devices have been used in hydropower station and Weijing plant trial, and after a longer period of operational tests. Improved, first adopted in large turbine units. The range of automatic control is as follows: (1) Parallel start-up of the same period; (2) Shutdown; (3) Operation of gas phase change; (4)
