As shown in figure 5, surveyed for a kind of reactor protection system function based on emulation platform provided in an embodiment of the present invention
Middle logic chart is put in trial assembly, in particular a kind of hydraulic pressure nuclear power station, using the pressure height of voltage-stablizer 1010 cause emergency shut-down logic as
Example illustrates, and the substantially implication of the logic chart will for three sensors 1020,1030,1040 of the measurement pressure of voltage-stablizer 1010
Pressure value is sent into reactor protection system respective logic module 1050,1060,1070, and protection system is by threshold calculations, and then 3
Take 2 votings triggering emergency shut-down action (logical-arithmetic unit 1080).
Obtain in reactor protection system device for testing functions after logic chart, just directly building in computer simulation platform
Mathematical modeling corresponding to the logic chart is found, in order to express easily, is only illustrated below with the Simulink modelings in Matlab,
Other computer platforms use similar mode, and it is no longer repeated.
In Simulink modules first in Matlab, it is right to directly find parameter input module 2010 corresponding to voltage-stablizer
Logic chart in reference picture 5 afterwards, three three sensors 1020,1030,1040 and reactor protection with pressure are found respectively

Primary Ioops pressure is 15.5MPa；
Main pump rotating speed is rated speed.
1st, Δ T overpower dynamic analysis
Fixed cold section of Tcold=292 DEG C of temperature, using slant function signal source, by hot arc temperature using 100s as the time from
Point (0~100s period is used for systems stabilisation original state) is slowly risen since 327 DEG C with 0.5 DEG C/s speed；Fig. 9
To obtain the oscillogram of Δ T, Δ T overtemperature protes line, Δ T overpower protective wires after being tested.It can be seen in figure 9 that Δ T
In 5s, Δ T overpower protective wires are above worn, it is meant that now Δ T ＞ Δs T overpower protection seting values, the super work(of Δ T now occurs
Rate protection causes emergency shut-down.Now cold section of Tcold=292 DEG C of temperature, Thot=329.4 DEG C of hot arc temperature, T=37 DEG C of Δ.
Hot arc rate temperature change is adjusted to 0.1 DEG C/s, other specification is constant, is tested, and obtained waveform is as schemed
Shown in 10, it can be seen that Δ T in 26s, above wears Δ T overpower protective wires, the protection of Δ T overpower now occurs and draws
Play emergency shut-down；Now Thot=329.6 DEG C of hot arc temperature, T=37.5 DEG C of Δ.
2nd, Δ T overtemperatures dynamic analysis
Fixed cold section of Tcold=310 DEG C of temperature, by hot arc temperature, using 100s as start time, (0~100s period is used
In systems stabilisation original state) slowly risen with 0.5 DEG C/s speed since 330 DEG C, obtained waveform is as shown in figure 11.From
As can be seen that Δ T is in 9s in Figure 11, Δ T overtemperature prote lines are above worn, Δ T overtemperature protes now occur and cause emergency shut-down.This
When Thot=334.5 DEG C of hot arc temperature, T=24.0 DEG C of Δ.
Hot arc rate temperature change is adjusted to 0.1 DEG C/s, other specification is constant, is tested, and obtained waveform is as schemed
Shown in 12.
In figure 12 it can be seen that Δ T in 75s, above wears Δ T overtemperature prote lines, Δ T overtemperature protes now occur and cause
Emergency shut-down.Now Thot=337.5 DEG C of hot arc temperature, T=27.4 DEG C of Δ.
Above-mentioned analysis result is summarized, the staticaanalysis results that contrast is carried out using the method manually calculated are as follows：
In static analysis, the time response for adjusting value function is not introduced, it is ideally that it, which acts setting valve,
Setting valve, it can not be expected actuation time.And in dynamic analysis, the time response for adjusting value function is introduced, action is played and adjusts
It is value and actuation time, related to hot arc rate temperature change.
