Analysis of Mexican power market and distribution transformer Market in 2021
Writer： Hengfeng you electric Time：2023-04-13 views：times
Mexico is located in the south of North America. The National Power Corporation (CFE) still plays a leading role in the Mexican power industry, with 92% of the power generation capacity and all the transmission and distribution systems, as well as all geothermal power generation and nuclear power capacity. CFE owns the national grid of Mexico and provides integrated services of power generation, transmission and distribution. By 2013, it has 169 home appliance plants with a total capacity of 44270mw and a total length of 41623km. In recent years, with the rapid growth of power demand in Mexico, the supply of natural gas for power generation is in short supply. In addition, the transmission facilities are old and the investment lags behind. Mexican energy experts recently warned that the power shortage crisis is approaching Mexico. On December 28, 2020, the blackout led to 10.3 million people without power for up to two hours. Reuters quoted Mexico's national energy control center as saying that the "imbalance between power load and power supply" led to the blackout, and the Mexican power network lost 7500 MW due to the blackout. In order to minimize the risk, "automatic protection system (after power failure) is activated".
In order to meet the demand of the national power industry, Mexico has to import 1 billion cubic meters of natural gas from the United States every day. With the new power station put into use, Mexico's natural gas demand will increase at an annual rate of 10% in the next five years, and the natural gas supply will be more and more tight. According to the report provided by Mexico's Ministry of energy, in order to meet the needs of an average annual growth of 5.6% of Mexico's power consumption in the next decade, Mexico's investment in the power field will reach 583 billion pesos (about US $52 billion) in the next decade, of which 38.8% will be used for the construction of power stations, 22.2% for the construction of transmission network infrastructure and 23.3% for the construction of distribution network, 12.8% for maintenance works and 3.4% for other investment projects included in the budget.
Mexico issued a new standard for distribution transformers in 2014. The new mandatory safety and energy efficiency standard nom-002-sede / ener-2014 for distribution transformers was published in the official gazette, which is applicable to domestic and imported distribution transformer products, including rod transformers, station transformers, desktop transformers and submersible transformers. The new standard will take effect on December 29, 2015, replacing the current standard nom-002-sede-2010. According to the new standard, the desktop transformer specified in nmx-j-285-ance-2013, the submersible transformer specified in nmx-j-287-ance-1998 and the rod transformer specified in nmx-j-116-ance-2005 shall meet the short circuit requirements specified in section 5.8 of nmx-j-116-ance-2005. In addition, the transformer shall be composed of sealed tanks to prevent leakage of insulating fluid. The efficiency of the transformer depends on the rated power of the equipment and whether it is a single-phase or three-phase transformer. At the same time, the standard also stipulates the energy loss requirements, test methods, sampling and acceptance standards, labels, instructions, quality assurance and conformity assessment procedures of transformers.
The United Power Grid of Mexico supplies power for 97% of its population. The power grid is divided into four parts: Northern Power Grid, northern Baja California power grid, southern Baja California power grid and southern power grid. Among them, Southern Power Grid Company is the largest power grid company, and the north is connected to Texas in the United States. In July 2000, a new transmission line connecting Texas of the United States and pidras of Mexico adopted HVDC technology. The State Grid is operated by the State Power Corporation (CFE). The total length of 150 ~ 400 kV transmission lines is 32200 km, and the total length of 6.6 ~ 138 kV secondary transmission lines and distribution lines is 541672 km. CFE plans to cooperate with abb to build a 750 km long high-voltage transmission system, including 5 transmission lines and 4 substations, using optical fiber control.
Therefore, for the smooth export of products, Jack, sales director of hengfengyou electric, reminded relevant power enterprises: first, pay close attention to the update of relevant safety and energy efficiency regulations in the new standards of importing countries; Second, put into action as soon as possible, seize technological innovation, accelerate the research and development of energy-saving and consumption reduction methods, adopt energy-saving and environment-friendly raw materials, and ensure the safety and quality of products at the same time; Third, do a good job in energy efficiency evaluation according to the requirements of energy consumption standards of importing countries before the effective date. Hengfengyou Electric has many years of experience in exporting Mexican dry-type transformers, Mexican oil immersed transformers and Mexican pole transformers, and has many local agents and distributors.
