Abstract

The embodiment of the invention provides a controller board card for a reactor protection system of a nuclear power plant and a control method. The controller board card comprises a memory and a processor. The memory is used for storing application information including a unique address of a current controller board card, information of a controllable device of the current controller board card, and information of a function set for a port of the controllable device by the current controller board card. The processor is used for setting an address for the port of the controllable device according to the unique address of the current controller board card after the current controller board card is inserted into the controllable device and setting the function for the port of the controllable device based on the information of the function set for the port of the controllable device. Therefore, the types and the number of the controller board card as well as the spare part number of the controller board card can be reduced; and management and maintenance of the reactor protection system of the nuclear power plant can be simplified.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of nuclear power, and in particular to a controller board and a control method for a reactor protection system of a nuclear power plant. Background technique [0002] The requirements of high reliability, high availability and high security for the instrument and control system of nuclear power plants make the digital control and protection technology of nuclear power plants become the technological frontier of the development of contemporary control systems, and the reactor protection system plays an important role in it. The reactor protection system monitors parameters related to reactor safety. When these parameters exceed the preset protection value, the reactor protection system automatically triggers an emergency shutdown and activates corresponding special safety facilities to limit the development of the accident and reduce the consequences of the accident. Prevent the rele...
