Will the launch of the world's largest floating wind power project affect the relay power market
The first typhoon unit of the Hywind Tampen floating offshore wind project, which will provide partial power to the Snorre and Gullfaks offshore fields near Norway, has been lifted.
The wind farm will consist of 11 Siemens Gomesa wind turbines of 167-8.6MW, with turbines of 167m in diameter and 81.5m in blades.
The Hywind Tampen floating offshore wind project has been upgraded to a total capacity of 95MW (originally planned to install 11 8MW Siemens Gamesa turbines with a total capacity of 88MW), with the aim of providing partial power to five offshore oil and gas operating platforms near Snorre and Gullfaks in the Norwegian North Sea. It is the world's first floating wind farm to power offshore oil and gas platforms. The project adopts concrete column substructure (SPAR). Reference video | a cup speak to understand, the world's largest floating type wind power projects.
The Hywind Tampen uses a concrete column type (SPAR) structure developed by Kværner. The following two videos explain the principles of the floating foundation and the detailed construction process of the substructure, which are easy to understand and worth watching.
The Tampa project is 140 kilometers offshore in water depths of 260-300 meters with a total investment of nearly $500 million. The project will be fully operational by the third quarter of 2022.
Wind turbines: 11 Siemens Gamesa SG-8.0-167 DD wind turbines (upgraded to 8.6MW wind turbines) with rotor diameter of 167 m, blade length of 81.5 m, and sweep area of 21,900m2.
Cable: 2.5 km long, 66 kV dynamic array cable system connected in loops. JDR Cable System will supply cables for the project at its Hartlepool, UK, plant. Subsea 7 AS will be responsible for installing cables and connecting them to oil and gas platforms.
Power output: Meets about 35% of the annual power needs of the Snorre A and B and Gullfaks A, B and C oil platforms in the North Sea. Wood Group will be responsible for retrofitting two oil and gas platforms.
Employment: 1,550 to 3,000 direct or indirect full-time equivalents. Kværner has 250 full-time construction jobs.
Reduced CO2 emissions: more than 200,000 tonnes, equivalent to the emissions of 100,000 cars.
Market Analysis of relay power
Industry competition and marketization degree: relay industry development is more mature, the market competition is more sufficient, major producing countries including China, the United States, Japan, Germany, etc., including the United States, Japan, Germany enterprise occupies most of the high-end relay market share, is mainly used in industrial automation control, automotive, communications, aerospace and other fields. The output of relays of Chinese enterprises accounts for about half of the global output of relays, but they are mainly medium and low-end products, which are mainly used in household appliances, electricity, automobiles and other fields.
Basic principles and classification of relay power
Basic concept and principle of relay: relay is a control component that automatically disconnects when the input parameters (such as electricity, magnetism, light, heat, sound and so on) in the circuit reach a specified value, which can make the output parameters of the circuit change in a predetermined step. In circuits, relays mainly control, protect, regulate and transmit information. The relay has an induction mechanism that reflects external input parameters, an executive mechanism that realizes "on" and "off" control of the controlled circuit, and an intermediate comparison mechanism that compares, judges and converts the size of the input.
As a control element, relays have the following functions:
(1) Expand the control range, such as multi-contact relay control signal reaches a certain value, according to the different forms of the contact group, at the same time open and close the multi-circuit;
(2) amplification, such as sensitive relay, intermediate relay, etc., with a very small amount of control, can control a large power circuit;
(3) comprehensive signals, such as when multiple control signals are input into the multi-winding relay in a specified form, after comparison and synthesis, to achieve the predetermined control effect;
(4) Automatic, remote control, monitoring, such as the relay on the automatic device and other electrical appliances together, can form a program control circuit, so as to realize automatic operation.
In the competition of the relay power market, enterprises in the United States, Japan and other developed countries constantly consolidate their dominant position in the global market by establishing technical standards, controlling core technologies, strengthening the integration of industrial chains, and firmly mastering the dominance of technical standards and international rules. In recent years, in order to further strengthen the core competitiveness, enterprises in the United States, Japan and other developed countries continue to expand relay power products and speed up technology integration. Their business scope has broken through simple relay manufacturing and developed to industrial control, system integration and other fields. The key to the competition in the high-end field has developed from the competition of quantity to the competition of the basic research and development of new relays, key materials, special equipment and other core products.
The raw material of the relay power
The relay power cost of relay is mainly determined by raw materials, which are mainly iron, silver, copper and other metals, accounting for about 74.4% of the production cost, labour and manufacturing costs accounting for 13.7% and 11.9% respectively, silver, copper and iron materials accounting for 36%, 21% and 7% of the raw material cost respectively. The price of three raw materials has a certain impact on the profitability of the whole industry. In addition to the main metal raw materials of the relay power, engineering plastics and enamelled wire are also important components of relays, and the overall supply of raw materials is stable at present.
The application domain of the relay power
The rapid development of relay power emerging relays. The application field of relays has changed from traditional application fields, such as household appliances and power automation control equipment, ships and new energy. Relay products have been transformed from low-end products to high-end products, such as high-voltage DC relay, high-performance industrial control relay, low-power energy-saving relay, new-generation communication relay, high-frequency relay, relay control components and other high-performance relays. The value chain of the relay industry is constantly extending to the high-end. In terms of product performance, it is developing towards the direction of more sensitive (low power consumption), smaller volume and higher performance (such as high-frequency relay).
