This project belongs to the field of power and electrical engineering. Modern ships and ocean platforms are developing in the direction of ultra-large and resistant to severe ocean weather, and their power system capacity has doubled; the capacity of electric propulsion ships has increased by more than 10 times, and the capacity of propulsion motors exceeds the capacity of generators. The power system creates high power density in the narrow cabin space of ships and offshore platforms, creating strong nonlinear coupling between generators and between generators and electrical loads. Existing technologies at home and abroad are based on classic control and relay protection, which show problems such as large dynamic fluctuations in power grid voltage/frequency, light load decoupling of generators, and weak control capabilities in the event of faults, which affect ship navigation and offshore platform operations, and in serious cases threaten the lives of people. After more than ten years of school-enterprise cooperation, the research team has carried out research on fault tolerance control of marine generators, fault diagnosis of power system disconnection, and fault tolerance technology of marine distribution boards based on the particularities of ships and platforms with the goal of reliable operation of power generation and distribution. Effective methods have been achieved on the reliability technology of automatic power generation and distribution of power systems that supports the safety of ships and offshore platforms, power generation and distribution products with independent intellectual property rights have been formed, and results have been achieved in the manufacturing and upgrading of domestic ship electrical equipment; Produce innovative results in three aspects. 1)Intelligent fault-tolerant control technology for diesel generators on ships and offshore platforms: Applying nonlinear control and chaos theory of the power system, the decoupling caused by chaotic oscillation when generators are running in parallel with light load is discovered for the first time. A three-dimensional autonomous system model of chaos and random fractal of the ship's power system is proposed., solving the problem of generator decoupling when ships are sailing on the channel; An intelligent fault-tolerant control method for generators based on neural network model reference adaptive and identification was invented, and a local recursive chaotic neural network was designed for generator modeling, reducing the model calculation amount by 30%. 2)Fault diagnosis and recovery and reconstruction technology for ship and offshore platform power systems: LDquo; Fault diagnosis + recovery and reconstruction rdquo; is used to implement control; correlation dimension identification is used to obtain the mapping between symptoms and faults, and C-C and GP algorithms are used to calculate the correlation dimension of the eigenmode function components of each working condition to implement fault diagnosis. A power system BDI (Belief-Desire-Intention) multi-agent fault reconstruction method is invented, which uses the BDI multi-agent ldquo; belief rarr; intention rbd; reasoning logic to generate a reconstruction strategy that meets system constraints and implement control for regional distribution systems. 3)Redundancy and fault-tolerant technology for power distribution boards of ships and offshore platforms: Using fault-tolerant technologies such as PLC redundancy, power supply redundancy and ring communication network, a power management distribution board with independent intellectual property rights for power system fault redundancy for ships and offshore platforms has been manufactured., a drawer and cabinet control panel that can be tested and maintained in a live state has been developed to ensure uninterrupted power supply; a sequential starting method for a single frequency converter with multiple motors has been designed to reduce the impact of starting motors with load on the power grid.

The product has been certified by the European Union and certified by famous classification societies such as the United States and France. Since 2005, it has been used on 1291 ships and 90 offshore platforms, with an output value of approximately 1.28 billion yuan; in the past three years, the output value has been approximately 289 million yuan, with a market share of 20% domestically and globally. About 8.4%; It has been applied to the Xuelong polar research vessel of China Polar Research Center, the 981 offshore deepwater semi-submersible drilling platform of China National Offshore Oil Corporation, and the 300,000-ton floating production and storage vessel of SBM Offshore Company of the Netherlands, the world's largest FPSO operator, promoting the application of my country's ship power generation and distribution equipment to international high-end ships and offshore platforms. After searching for the level of scientific and technological achievements of the Shanghai Institute of Science and Technology Information, the overall project results have reached the international advanced level.
