Embodiment 1

[0073] see figure 2 and image 3 , the embodiment of the present invention provides a rod control and rod position system 1000 for nuclear power plants, including:

[0074] a control rod assembly 1100 for controlling the reaction of the nuclear reactor;

[0075] rod control subsystem 1200, including a control rod drive mechanism 1210 for driving the control rod assembly 1100;

[0076] The rod position subsystem 1300 is used to measure the control rods of the control rod assembly 1100 to generate rod position information;

[0077] And the detection subsystem 1400, which is respectively connected with the rod control subsystem 1200 and the rod position subsystem 1300, is used to detect the working current of the control rod drive mechanism 1210 in real time, and according to the rod position information of the rod position subsystem 1300, control the rod control. Faults in the system 1200 are diagnosed.

[0078] The control rod driving mechanism 1210 is used as a key part o...

Embodiment 2

[0091] see Figure 4 to Figure 6 and combine figure 2 and image 3 , the present invention is used for the fault diagnosis method of the rod control and rod position system of nuclear power plant, comprises steps:

[0092] S100, using a DC power supply to supply power to the control rod drive mechanism 1210 of the rod control subsystem, the control rod drive mechanism 1210 drives the control rods according to the control signal sent by the rod control subsystem 1200, and the rod position subsystem 1300 measures the rod position of the control rods and processes and generates bar position information;

[0093] S200. The detection subsystem 1400 detects the working current of the control rod drive mechanism 1210 in real time, obtains the rod position information generated by the rod position subsystem 1300, and diagnoses the fault of the rod control subsystem 1200 according to the rod position information and real-time current.

[0094] The operating current of the control r...

Abstract

The invention discloses a rod control and rod position system for a nuclear power station and a fault diagnosis method of the rod control and rod position system, and relates to the technical field of nuclear power. The rod control and rod position system for the nuclear power station comprises a control rod assembly, a rod control subsystem and a rod position subsystem, and further comprises a detecting subsystem, wherein the control rod assembly is used for controlling reaction of a nuclear reactor; the rod control subsystem comprises a control rod driving mechanism for driving the control rod assembly; the rod position subsystem is used for conducting measurement on a control rod of the control rod assembly to generate rod position information; the detecting subsystem is connected with the rod control subsystem and the rod position subsystem, is used for detecting the working current of the control rod driving mechanism in real time, and is used for diagnosing faults of the rod control subsystem. Through the arrangement of the detecting subsystem, a user or machine can obtain the fault information of the control rod driving mechanism in time.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a rod control and rod position system for a nuclear power plant and a fault diagnosis method thereof. Background technique [0002] The rod control and rod position system used in nuclear power plants is one of the important special instrument and control systems of nuclear power plants. During the start-up, power conversion and shutdown process of nuclear power plants, it is necessary to control the control rods through the rod control and rod position system used in nuclear power plants. Drive mechanism to control the reaction of the control rods with the reactor. It can be seen that the rod control and rod position system used in nuclear power plants plays a vital role in the safety and economic benefits of nuclear power plants. [0003] The existing rod control and rod position systems for nuclear power plants mainly include: [0004] The control rod assembly is used ...
