A method for checking logic of a safe power supply system for returning to a port

Abstract

This invention discloses a logic verification method for a power supply system that meets the requirements for safe return to port. This method verifies the relevant load equipment on a ship that is essential for safe return to port. The logic verification method includes: acquiring relevant electrical equipment information of the load equipment; determining the division zone where the load equipment is located; the division zone being formed according to the requirements for safe return to port; and verifying that the division zone of the load equipment corresponds to the division system of the power supply system corresponding to the load equipment, as defined by the requirements for safe return to port. The division system is formed by the power supply system according to the requirements for safe return to port and corresponds to the division zone. Under safe return to port conditions, it verifies whether the necessary load users meet the power supply requirements for safe return to port. If they do, the verification is correct; otherwise, it is incorrect. Then, the power distribution system can be modified until the power supply circuit meets the system requirements under the conditions for safe return to port.

Description

Technical Field

[0001] This invention relates to the field of ship safe return to port technology, and in particular to a logic verification method for a power supply system that meets the requirements for safe return to port. Background Technology

[0002] For power distribution systems, the design focus and objective is to ensure power supply to critical systems. Terminal loads are supplied with dual redundant power sources, typically with two main switchboards located in different Class A compartments. If one main switchboard in a Class A compartment fails, the other main switchboard in the Class A compartment has the capacity to supply power to the critical equipment or systems in need. However, for passenger ship power distribution systems, in addition to redundant distribution, the power distribution for safe return to port must also be considered. In the 14 critical systems involved in the safe return to port of passenger ships, the design process often fails because it only considers redundant distribution, ensuring that secondary circuits meet the safe return requirements within the same vertical zone, while neglecting the cross-supply of the primary power supply. This results in equipment and primary power supplies not being in the same compartment and belonging to the same safe return to port system.

[0003] Due to the large and complex power supply system of passenger ships, while considering redundant power distribution, if the equipment falls within the scope of the safe return-to-port system requirements, the common practice is to allocate main power and secondary power supply circuits to the load users in the initial stage of equipment power supply design. Currently, there is no open-source software or mature verification program to verify that the power supply equipment and power source are in the same compartment or belong to the same safe return-to-port system, and verification is rarely included in later safe return-to-port reports. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the present invention provides a logic verification method for a safe return-to-port power supply system. Under the condition of safe return-to-port, the method verifies whether the necessary load users meet the requirements for safe return-to-port power supply. If they do, the verification is correct; otherwise, it is incorrect. Then, the power distribution system can be modified until the power supply circuit meets the system requirements under the condition of safe return-to-port.

[0005] This invention provides a logic verification method for a power supply system that satisfies the requirements for safe return to port, used to verify relevant load devices on a ship that are essential for safe return to port. The logic verification method includes:

[0006] Obtain relevant electrical equipment information of the load device, determine the division zone where the load device is located, and the division zone is formed according to the safe return to port requirements;

[0007] If the zone where the load device is located corresponds to the zone system of the power supply system corresponding to the load device according to the safe return to port requirements, then the verification passes;

[0008] The division system is formed by the power supply system based on the requirements for safe return to port, and each division corresponds to a division zone.

[0009] In some embodiments of the present invention, the method for verifying the logic of a safe return-to-port power supply system further includes:

[0010] If the zone where the load device is located does not correspond to the zone system of the power supply system corresponding to the load device as defined by the safe return-to-port requirements, the verification will fail.

[0011] In some embodiments of the present invention, if the verification fails, the method further includes:

[0012] Modify the power supply circuit corresponding to the load device that fails the verification, so that the load device with the modified power supply circuit can pass the verification.

[0013] In some embodiments of the present invention, the relevant electrical equipment information includes at least the installation location, power supply voltage, current, frequency, power consumption, connecting cable information, and power distribution cabinet information.

[0014] In some embodiments of the present invention, the relevant electrical equipment information and information related to safe return to port are pre-stored in a database.

[0015] Compared with the prior art, the beneficial effect of the logic verification method for a safe return-to-port power supply system provided by the embodiments of the present invention is that, under the condition of safe return-to-port, it verifies whether the necessary load users (load equipment) meet the requirements for safe return-to-port power supply. If they meet the requirements, the verification is correct; otherwise, it is incorrect. Then, the power distribution system can be modified until the power supply circuit meets the system requirements under the condition of safe return-to-port. Attached Figure Description

[0024] This invention provides a method for verifying the logic of a power supply system necessary for safe return to port, used to verify relevant load devices on a ship that are essential for safe return to port. Figure 1 As shown, the logic verification method includes:

[0025] Obtain relevant electrical equipment information of the load device, determine the division zone where the load device is located, the division zone is formed according to the safe return to port requirements, wherein the relevant electrical equipment information includes at least the installation location, power supply voltage, current, frequency, power consumption, connecting cable information and power distribution cabinet information;

[0026] If the zone where the load device is located corresponds to the zone system of the power supply system corresponding to the load device according to the safe return to port requirements, then the verification passes;

[0027] The division system is formed by the power supply system based on the requirements for safe return to port, and each division corresponds to a division zone.

[0028] In this embodiment, the logic verification method for ensuring a safe return-to-port power supply system further includes:

[0029] If the zone where the load device is located does not correspond to the zone system of the power supply system corresponding to the load device as defined by the safe return-to-port requirements, the verification will fail.

[0030] Furthermore, if the verification fails, the method further includes: modifying the power supply circuit corresponding to the load device that failed the verification, so that the load device after the power supply circuit is modified can pass the verification.

[0031] The relevant electrical equipment information and information related to safe return to port are all stored in the database in advance.

[0032] In the maritime field, when discussing power distribution systems and the safe return to port, systems A and B are involved and defined, such as... Figure 1 The diagram shown is a simplified power line diagram in the logic verification method for a safe return-to-port power supply system provided in this embodiment. Under normal circumstances, main power supplies A1 and B1 can cross-power the entire ship. As can be seen from the diagram, A1 supplies power to secondary distribution boxes 6 and 7; B1 supplies power to distribution boxes 2 and 4. When designing the power supply circuit for the load, two aspects are considered:

[0033] If the equipment is not part of the safe return-to-port system, then the safe return-to-port design will not be considered, and there are no special requirements for power distribution.

[0034] When equipment 2 is a necessary system for safe return to port, the large and complex power distribution system can easily lead to errors in design. Initially, power supply to loads C, D, E, and F from the secondary distribution box is considered, as they are all in the same vertical zone, which is fine. However, checking the power supply circuits upwards reveals a problem: distribution box 2 is powered by system B, and distribution box 6 is powered by system A. This results in load C, which belongs to system A, being powered by system B, failing to meet the power distribution requirements for safe return to port. The same applies to E. Loads D and F are fine.

[0035] However, simply considering the primary and secondary circuits during the design phase is insufficient and lacks rigor in addressing the aforementioned issues. Therefore, after the ship's power distribution is completed, verification is essential when considering the safe return to port scenario.

[0036] See Table 1 for details.

[0037] Table 1, Electrical Equipment Database

[0038]

[0039]

[0040] In Table 1, C, D, E, and F represent four different electrical loads, which can be motors or distribution cabinets from other systems. While C, D, E, and F have specific locations, for simplicity, Table 1 defines these locations as Zone A and Zone B based on safe return-to-port requirements, corresponding to the positions in the fore and aft engine rooms. The main and secondary power distribution circuits are also divided into systems A and B according to safe return-to-port requirements.

[0041] For clarity, we have simplified the electrical database and extracted the key verification information, as shown in Table 2.

[0042] Table 2, Verification Table

[0043]

[0044] Table 2 clearly shows that there are no problems when the safe return-to-port system for loads C, D, E, and F matches the corresponding power supply system. Based on the above logic, we can define a rule in Excel to verify the safe return-to-port power distribution system. As shown in Table 3,

[0045] Table 3, Verification Rule Table

[0046]

[0047] In this process, C represents the load to be checked. Its location and safe return information are obtained from a database. Conditions are then set in the results to match the safe return system and power supply information, outputting correct and incorrect results. This achieves the verification purpose, thereby correcting erroneous power supply circuits to ensure the power supply system meets the safe return requirements.

[0048] As can be seen from the above technical solutions, the logic verification method for a safe return-to-port power supply system provided by the above embodiments of the present invention verifies whether the necessary load users (load devices) meet the safe return-to-port power supply requirements under the condition of safe return-to-port. If they meet the requirements, the verification is correct; otherwise, it is incorrect. Then, the power distribution system can be modified until the power supply circuit meets the system requirements under the condition of safe return-to-port.

[0049] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
