Embodiment 1

[0058] figure 1 It is an implementation flowchart of a steam generator water level early warning method provided by an embodiment of the present invention. The details are as follows:

[0059] In step S101, obtain real-time data and key parameters of the water level of the steam generator;

[0060] Among them, the key parameters include steam generator water level, steam generator water level setting value, steam generator steam flow and main feed water flow, steam water pressure difference, steam generator blowdown flow, auxiliary feed water flow, auxiliary feed water tank water level or one of Its combination.

[0061] In step S102, it is detected whether the key parameter meets a preset key parameter early warning condition;

[0062] In step S103, if the key parameter satisfies the key parameter early warning condition, receive the input steam generator water level control command through the operation entrance of the steam generator water level control main interface;

[0063] In s...

Embodiment 2

[0071] figure 2 It is the implementation flow chart of step S103 of the steam generator water level early warning method provided by the embodiment of the present invention. The details are as follows:

[0072] Step S201, if the key parameter satisfies the key parameter warning condition, display the warning result;

[0073] Step S202, receiving the inputted steam generator water level control command through the operation entrance of the steam generator water level control main interface.

[0074] In the embodiment of the present invention, the early warning result is displayed, the operator can intuitively, comprehensively and quickly obtain relevant parameters, and determine the cause of the abnormality of the steam generator water level, and realize quick intervention through the operation entrance of the steam generator water level control main interface.

Embodiment 3

[0076] The embodiment of the present invention describes the implementation process of step S104 of the steam generator water level early warning method, which is detailed as follows:

[0077] Using the preset super real-time acceleration mode and the real-time data, according to the steam generator water level control command, accelerate the execution of the steam generator water level control operation corresponding to the steam generator water level control command, and obtain the steam generation in advance The operation effect of the water level of the device.

[0078] In the embodiment of the present invention, the operation effect of the water level of the steam generator is obtained in advance, which provides a time buffer for the correct judgment and operation of the operator, and the operator can control and adjust the water level of the steam generator more accurately.

Abstract

The invention discloses a vapor generator water level forewarning method and device. The vapor generator water level forewarning method comprises: acquiring realtime data and key parameters of a vapor generator water level; detecting whether the key parameters meet pre-set key parameter forewarning conditions; if the key parameters meet the pre-set key parameter forewarning conditions, receiving an input vapor generator water level control instruction through an operation access of a vapor generator water level controlling main interface; performing super-realtime simulation on the vapor generator water level by using a pre-set super-realtime acceleration mode, the realtime data and the vapor generator water level control instruction, so as to obtain a vapor generator water level operation effect ahead; and according to the operation effect, pre-judging the effectiveness of the vapor generator water level control instruction. Compared with methods and devices in the prior art, the vapor generator water level warning method and device pre-judge the effectiveness of the vapor generator water level control instruction through the acceleration function, and provide a theory basis for correct operations of operators.

Description

Technical field [0001] The invention belongs to the field of nuclear power control. More specifically, the invention relates to a steam generator water level early warning method and device. Background technique [0002] The steam generator is an important nuclear power device in a nuclear power plant. In a nuclear power plant, the water level of the steam generator must be controlled to a known setting value to ensure the safe operation of the nuclear power plant. [0003] At present, the feedwater flow control system of the steam generator ensures that the water level measured by the second circuit of the steam generator is maintained at the set value by controlling the feed water flow to the steam generator. The operator can complete the adjustment of the water level of the steam generator through the man-machine interface of the steam generator water level control system. [0004] However, the current steam generator water level control system has at least the following shortcom...
