DO810 3BSE008510R1 Digital electro-hydraulic control system for steam turbines

Application and promotion of DO810 3BSE008510R1 in turbine control. In the past, most of the turbine control used the traditional machine-hydraulic or hydraulic regulating and protection system, which had the disadvantages of low automation, poor control accuracy, high failure rate, complicated operation, and difficult maintenance and repair. In the late 1980s and early 1990s, China began to draw on and independently develop DEH systems with independent intellectual property rights, which triggered a transformation of the control system of domestic power station turbines.

DO810 3BSE008510R1 is applied to new and rebuilt steam turbine units of various models in the range of 3MW to 1000MW, and its application performance has exceeded more than 1,500 sets. The control strategy of modern turbine control system is developed on the basis of traditional basic control strategy, taking into account the needs of power grid control, heat network control and coordinated control of machine and furnace, and the digital electro-hydraulic control system DEH is a typical form of modern turbine control system.

DO810 3BSE008510R1 is a steam turbine DEH system designed based on the FM hardware series of HOLLiAS MACS system. T800F has a strong capability of expanding the monitoring and control of the main engine and auxiliary engine system of the steam turbine, and it can be used to develop a variety of more advanced control functions for the steam turbine according to the needs of different users, applicable to the control system of steam turbines under 300MW, and it has the characteristics of high cost performance. It is suitable for turbine control system under 300MW and has the feature of high cost performance.
