Embodiment 1

[0058] figure 1 It is a flow chart of the implementation of the steam generator water level early warning method provided by the embodiment of the present invention, and is described in detail as follows:

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

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

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

[0062] In step S103, if the key parameter meets the key parameter early warning condition, the steam generator water level control command input is received through the operation entry of the steam generator...

Embodiment 2

[0071] figure 2 It is the implementation flowchart of step S103 of the steam generator water level early warning method provided by the embodiment of the present invention, and is described in detail as follows:

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

[0073] Step S202, through the operation entry of the steam generator water level control main interface, an input steam generator water level control instruction is received.

[0074] In the embodiment of the present invention, the early warning result is displayed, and the operator can intuitively, comprehensively and quickly obtain relevant parameters, and judge the cause of the abnormal water level of the steam generator, 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 described in detail 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, the steam generator water level control operation corresponding to the steam generator water level control command is accelerated to 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

A steam generator water level warning method and device are provided. The method comprises: obtaining real-time data of a steam generator water level and a key parameter (S101); detecting whether the key parameter meets a preset key parameter warning condition (S102); if the key parameter meets the key parameter warning condition, receiving an input steam generator water level control instruction by means of an operation interface of a steam generator water level control main interface (S103); performing faster-than-real-time simulation on the steam generator water level by means of a preset faster-than-real-time acceleration mode, the real-time data, and the steam generator water level control instruction, to obtain an operation effect of the steam generator water level in advance (S104); and predetermining, according to the operation effect, effectiveness of the steam generator water level control instruction (S105). The method and device of the present invention predetermine the effectiveness of the steam generator water level control instruction by means of an acceleration function, providing a theoretical basis for an operator to implement a correct operation.

Description

technical field [0001] The invention belongs to the field of nuclear power control, and 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 plant in a nuclear power plant. In a nuclear power plant, the water level of the steam generator must be controlled to a known set value to ensure the safe operation of the nuclear power plant. [0003] At present, the steam generator water level control system (Feedwater Flow Control) ensures that the water level measured by the secondary circuit of the steam generator is maintained at the set value by controlling the feedwater flow to the steam generator. The operator can complete the adjustment of the water level of the steam generator through the human-computer interaction interface of the steam generator water level control system. [0004] However, the current steam generator water level control sy...
