Description

The main objective of this thesis was to investigate the feasibility of implementing simulator and computational applications in FPGA-based hardware. This with the goal of determining whether the processing power of the Stressometer control system can be increased through the use of the FPGA device technology. However, in addition to these two applications there are also an interest in finding out whether it is feasible to implement control applications in FPGAbased hardware or not. Accordingly, such a feasibility study can be a suitable continuation of this thesis. Common for both types of applications, simulation and computation, are the need for a suitable communications infrastructure, an issue which was not addressed in this thesis. The need for external communication is central if the applications are to be implemented in a final product.

This since e.g. a user needs to be able to control the Stressometer measuring roll simulator and the Stressometer control system needs to be able to send and receive matrix elements to and from the Cholesky component. Even though demands on bandwidth, latency, resource consumption, etc., varies between the different applications, it might be advantageous to find a general communications infrastructure that can be used with all applications. This reduces future development costs and increases the portability of the various FPGA-based applications. In order to be able to use the FPGA device technology to increase the processing power of the Stressometer control system, a suitable interface between these is needed. Accordingly, an investigation should be performed with the aim of finding a general interface that can be used to add external FPGA-based hardware accelerators to the Stressometer control system.

Such an interface should facilitate portability, upgrades and changes in hardware configurations during run-time. This while meeting the communications demands, such as bandwidth and latency requirements, of the various applications. By requiring that the interface between the FPGA-based hardware accelerators and the Stressometer control system facilitates changes in the hardware configurations, the use of hardware/software co-design can be investigated. Through the use of hardware/software codesign, suitable hardware/software partitions can be determined for the various configurations of the Stressometer system. In addition to this, hardware/software partitioning can also be performed during run-time, moving applications between hardware and software or even between different hardware technologies, to reflect the changing needs of the system.

Emergency handling measures for DCS system:
(1) When all operator stations fail (all upper computers have a black screen or crash), as the unit is not equipped with backup hard manual operation and monitoring instruments, immediate shutdown and boiler shutdown measures should be taken.

(2) When the communication network of the decentralized control system malfunctions, causing all data to be unable to be refreshed, measures such as immediate shutdown and boiler shutdown should be taken in case of all operator stations experiencing malfunctions.

(3) When the internal communication network of the main on-site control station fails or both the main and auxiliary control units (DPUs) fail (crash or power loss), and it is impossible to maintain the safe and reliable operation of the unit, immediate measures such as shutdown and boiler shutdown should be taken.

(4) When some operator stations fail and only a few operator stations can monitor and operate, the available operator stations should continue to maintain the stable operation of the unit. However, major operations should be stopped and the unit accident prediction should be made. At the same time, maintenance personnel should be immediately contacted for handling.

(5) When the DEH loses power and causes a turbine trip, it should be handled according to the turbine trip. If the turbine trip is not caused, the DEH should be switched to hard manual operation to continue maintaining stable operation of the unit. If there are no special circumstances at this time, the operation should be stopped and the unit accident prediction should be made. At the same time, immediately contact maintenance personnel for handling.

(6) After the auxiliary program control loses power, the operating personnel should try their best to stabilize the operation of the unit, strengthen monitoring, and immediately contact maintenance personnel for maintenance and handling. In the event that the operation cannot be maintained (the operating equipment trips and the backup equipment cannot be started), emergency measures should be taken to stop the operation of the unit. With the promotion and application of new technologies, the automation and intelligence of the DCS system are becoming increasingly perfect, and the safety and reliability of the system are also becoming higher, No matter how advanced the equipment is, from a reliability perspective, absolute reliability does not exist. Therefore, in a certain sense, having faults is absolute. However, the relationship between faults and accidents is not inevitable, and faults cannot be prevented.

The key is how to detect faults as soon as possible, and then prevent, control, and eliminate them to avoid further expansion of faults. At the same time, higher requirements are also put forward for thermal maintenance personnel, In order to ensure the safe and stable operation of the locomotive team, maintenance personnel should continuously strengthen their learning and conduct accident plan drills to reduce the occurrence of accidents and quickly handle them after they occur.
