Embodiment Construction

[0040] We first refer to figure 2 , wherein the processing unit 10, for example, a computer which is available to the user and / or is also capable of controlling the pumping device DP, in the example shown, comprises:

[0041] - an input interface 13 for receiving meteorological data (e.g. from a station 19) as well as hydrological data (tidal coefficient, high / low tide times, water level of a river or stream, flow rate, etc.) any network;

[0042] - input interface 14, to which the sensor CAP is connected (for example, via local area network, wired or wireless) in order to obtain on-site clogging data on the tank TAM,

[0043] - an output interface 15 for controlling the pumping device DP without operator intervention in a fully automatic execution,

[0044] - A processor 16 capable of cooperating with said input and output interfaces and a memory 17 (including persistent memory especially for instructions of a computer program in the sense of the invention and possibly tem...

Abstract

The present invention relates to a method of assisting in the management of a pumping device capable of supplying water from a natural water system to a circuit of a power production facility, the water upstream of the circuit containing water that may block one or more filters provided at the inlet of the circuit object. In particular, collect at least some parameters that are particularly relevant to the water system, which have an effect on the number of objects that tend to clog the filter, and: - in the previous step, at least based on a historical data related to said parameters to develop a statistical model (S2), - in the current step, at least current parameters related to the water system are collected, and the statistical model described above is used in conjunction with the current parameters to assess the risk of inflow of blocking objects (S6), And, - generating an alarm signal for deactivating the pumping device at a selected time (S7) according to the assessed risk.

Description

technical field [0001] The invention relates to the field of water supply pumping suitable for circuits of power production facilities. Background technique [0002] In some power plants, especially nuclear power plants, cooling is often provided using water taken from natural water systems (sea water, river water). This water is pumped through pumping means to inject it into the cooling circuit. [0003] However, this water may contain algae, marine sediment, river detritus, and more. Of course, the water usually needs to be filtered to prevent these objects from clogging the cooling circuit. For this purpose, filter cartridges are used upstream of the circuit. [0004] These barrels can be rotated to expel clogged objects (hereinafter referred to as "clogging agents"). The speed of rotation of the drum can be varied according to the degree of clogging. The degree of clogging can be measured by differential pressure or by the water level observed on both sides of the w...
