Problems solved by technology

During the commissioning test of the digital reactor protection system, a large number of signals need to be input according to the protection function logic to verify the system function. If the test signal is manually injected directly from the terminal block, a large amount of manpower is required to coordinate and implement synchronously, and it is difficult to achieve synchronous operation; If the analog signal is forced ...

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 and figure 2 As shown, a fully digital reactor protection system debugging device includes an upper computer and multiple lower computers. The upper computer and the lower computer are connected through Ethernet. The lower computer is set in the protection channel of the nuclear reactor protection system, and is connected with the DCS cabinet of the reactor protection system through an analog signal cable and a switch signal cable.

[0021] The number of host computers is 1-2. When using 2 upper computers, one of them is a standby computer. The upper computer adopts a portable PC.

[0022] The number of said lower computers is 1-10, with three ports of DI, DO and AO. The DI and DO ports are connected to the DCS cabinet of the reactor protection system through digital signal cables, and the AO port is connected to the DCS c...

Abstract

The invention belongs to the technical field of nuclear power plant reactor protection, specifically relates to a full-digital reactor protection system debugging device, and aims to develop and design a set of full-digital reactor protection system debugging device, realize batch analog input and digital input/output signal simulation simultaneously by establishing a work condition database quickly, and configure related test conditions according to the test procedures to speed up the progress of debugging. The debugging device is characterized in that the device comprises an upper computer and a plurality of lower computers; the upper computer and the lower computers are connected via the Ethernet; and the lower computers are arranged in a protection channel of a nuclear reactor protection system, and are connected with a DCS cabinet of the reactor protection system through an analog signal cable and a switching signal cable. The efficiency of debugging is improved greatly. The debugging time is shortened. A powerful time support is provided for power generation in power plants.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant reactor protection, and in particular relates to a fully digital reactor protection system debugging device. Background technique [0002] The reactor protection system is an important control to ensure the integrity of the reactor's three safety barriers (fuel cladding, primary circuit pressure boundary, and containment), to limit the reactor's operation within the allowable range or to mitigate the consequences of accidents, and to protect the reactor, the environment, and the safety of personnel. system. In the reactor protection system commissioning test, the logic function inspection (TP RPR 14), the protection channel response time measurement (TP RPR 15) and the overall system test of the reactor protection system before core loading (TP RPR 17), the system needs to be set to non-stop The actual output of the reactor and special action signals triggers the state of the physical...
