Embodiment Construction

[0045] In the following description, for the purpose of illustration rather than limitation, specific details such as specific device structures and techniques are presented for a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0046]Since the power supply system of nuclear power ships is faced with mixed power types (may include steam turbines, diesel engines, super capacitors and other power sources), cross operating conditions (need to consider both the reactor operating mode and the ship operating conditions), and changeable fault types, etc., The selection of the operation mode of the power system and the determination of the...

Abstract

The invention discloses a power supply mode selection method based on nuclear power ship operation condition analysis and device. The method comprises the following steps: S10, a ship operation condition and constraints under the ship operation condition are determined; S20, according to the ship operation condition, the operation mode of a reactor is determined; S30, according to the ship operation condition and the operation mode of the reactor, the current available power supply and the capacity, the load type and the power are determined; S40, according to the defense in depth principle ofa power supply and load characteristics of a nuclear power plant, the types and the number n of power supplies are selected; and S50, the capacity and the minimum load rate are verified, if passing the verification, the power supply system operation mode selected and determined by the former steps is determined to be a final result, and if not, adjustment is carried out according to a preset strategy, and the step S30 is carried out and reselection is carried out. The device is used for executing the method. Thus, nuclear power ship operation condition analysis and power supply system operation mode selection under each ship reactor operation condition are solved, and requirements of power supply safety, reliability and stability and the like are met.

Description

technical field [0001] The invention relates to the field of electrical technology in the design of nuclear power ships, in particular to a method and device for selecting a power supply mode based on the analysis of operating conditions of nuclear power ships. Background technique [0002] The analysis of ship stack conditions refers to the combing and analysis of the cross-working conditions of the nuclear power ship's ship operating conditions and reactor operating modes. The ship operating conditions include docking conditions, port entry and exit conditions, starting and Working conditions, dynamic positioning working conditions and external power transmission working conditions, the reactor operation mode includes all operation modes from the reactor complete discharge mode (RCD) to the reactor power operation mode (RP). The operation mode and depth sequence of the power supply system of a nuclear power ship refer to the power supply mode adopted by the power supply sy...
