Embodiment Construction

[0032] Such as figure 1 Shown, the method for the automatic processing of safety level DCS response time test data of the present invention comprises the steps:

[0033] Step 1. Input a set of analog signals to the reactor protection system through the working condition simulation device, and the reactor protection system performs threshold judgment after receiving the analog signals, and then outputs control signals after logic operation processing;

[0034] In the present invention, the working condition simulation device inputs analog signals to the RPC through two trigger channels 1 to trigger the protection action of the corresponding equipment, and the RPC sends the processed analog signals to the corresponding equipment through four output channels 2 .

[0035] Step 2. Use a waveform recorder to record a section of waveform between the input of the analog signal and the output control signal of the reactor protection system;

[0036] The waveform recorder simultaneousl...

Abstract

The invention discloses a method for automatically processing safety level DCS response time testing data in a nuclear power station. A simulated condition signal waveform file *.CSV recorded by a waveform recorder is automatically analyzed, and a corresponding phase step response point of each channel in each oscillogram can be determined, so that the response time of each output channel is determined. After multiple *.CSV files recorded under the same working condition are repeatedly analyzed, the files are summarized and screened, and the response time of the current equipment to be detected under the working condition is obtained. Due to computer automation and batch data analysis, a high-efficiency and reliable method is provided for analyzing the response time testing data of a reactor protection system.

Description

technical field [0001] The invention relates to a method for testing equipment response time in the field of control, in particular to a method for automatically processing test data of the safety level DCS of a nuclear power plant. Background technique [0002] In the CPR1000 reactor type nuclear power unit, the reactor protection system (referred to as RPS system) of the safety level DCS of the nuclear power plant performs the collection and protection functions of the reactor state parameters. When the system detects that the parameters of the reactor exceed the threshold, it will output a series of reactor protection actions (mainly including reactor jump actions and safety special actions) through voting logic. The physical components are connected as figure 1 As shown in , the waveform recorder is respectively connected with the working condition simulation device and the reactor protection system, and simultaneously receives the trigger signal output by the working c...
