National Grid is asking UK companies how much they can cut their electricity demand next winter to help keep the lights on.
According to foreign media reports, national Grid's network manager sent a request to some big companies last week asking how much they could be paid to reduce operations. The document did not say how many companies had been questioned.
With the gas crisis threatening the security of supply across Europe, The UK's National Grid is exploring all options to avoid blackouts this winter. Britain relies on gas for more than a third of its electricity generation. If Russia stops sending fuel to Europe and its reserves run dry, Britain's electricity supply could be at risk.
"In order to establish the feasibility of a commercial national demand service, the power system operator wants to know the total megawatt capacity of the supplier," the document states. According to the documents, National Grid has set a range of potential payments ranging from ￡100 ($121.41) per megawatt-hour to as much as ￡6,000.
National Grid is also developing a service to subsidize households for using less electricity at peak times. 27.8 million homes and small businesses have access to smart meters. Many companies have on-site power generation, such as diesel generators, as a backup in the event of a power outage. These can temporarily reduce the power demand on the grid. National Grid declined to comment.
Market Analysis of power relays
Time relay 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 power relays
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 power relays 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 power relays 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 power relays
The power relays 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 power relays, engineering plastics and enamelled wire are also important components of relays, and the overall supply of raw materials is stable at present.
The application of the power relays
The rapid development of power relays 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).
