Abstract : This paper describes the characteristics of modern electricity and the increasingly serious pollution caused by electricity. It compares and contrasts the relationship between electricity pollution and electromagnetic pollution. It also discusses the formation process of a new interdisciplinary field, "Electromagnetic Engineering." Keywords : Electricity pollution, Electromagnetic engineering. The title "Modern Electricity and Electricity Pollution" is derived from the reality of environmental pollution caused by modern industry. Electricity is a recognized clean energy source. However, it is well known that it also causes pollution. During the formation of electricity, there is conventional environmental pollution from flue gas and ash from thermal power plants, potential nuclear radiation pollution from nuclear power plants, and ecological balance problems that may arise from the construction of large hydropower stations. After electricity is formed, there is environmental pollution caused by electromagnetic radiation during transmission and transformation. Electricity has become an important part of economic development and social life. With the expansion of the scope of electromagnetic energy utilization and the increasing efficiency of energy utilization, the electromagnetic waves existing on Earth are constantly strengthening and have extremely wide frequency bands. Compared with cosmic clutter, these electromagnetic waves have a huge impact on human social life and the national economy. It not only directly affects the normal operation of electronic devices in various fields, causing information distortion and loss of control, but more seriously, under the long-term effects of high-intensity electromagnetic radiation, it can affect and harm the physiology and ecology of organisms, impacting human health and vitality. This also causes environmental pollution, the so-called electromagnetic smog. Electromagnetic smog and the electromagnetic pollution it causes have long attracted attention, research, and the application of engineering techniques to solve electromagnetic interference and its hazards, striving to reduce or eliminate pollution. As early as 1903-1904, Switzerland measured significant interference of the AC system to telephones in its railway sector. Before World War I, the American Society of Electrical Engineers (mEE) developed a "waveform standard," and in 1919 calculated the "telephone interference factor" to measure the interference of the power system to telephones. In 1934, the International Special Committee on Radio Interference (CISPR) was established. This committee has six subcommittees: A, B, C, D, E, and F, which respectively study six categories of objects and contents related to this: testing methods and instruments; testing standards for high-frequency equipment; high-voltage lines, power plants, substations, and other power sources; internal combustion locomotives and special electrical equipment; televisions and radios; and other household appliances. After its establishment, CISPR first conducted long-term research on measurement methods, interference standards, and suppression technologies, focusing on exploring the conditions for electronic and electrical equipment to coexist without interference, and made progress. In 1958, an organization called the Group on Radio Frequency Interference (C-RFI) renamed the Electromagnetic Compatibility Group (G-EMC) of the Institute of Electrical and Electronics Engineers (IEEE) as Radio Interference. In 1964, G-EMC was changed to EMC. However, after several revisions, "electromagnetic compatibility" was expanded to a broader range of fields. At the same time, EMC became the specific term for the coexistence of electronic devices and electrical equipment without interference. With the increasing severity of electromagnetic pollution, the deepening and development of research, and the progress, development, and improvement of engineering technologies for solving the problem, a new interdisciplinary field, "Environmental Electromagnetic Engineering" or "Environmental Electromagnetic Compatibility," has been established in the last two or three decades. This field conducts extensive and in-depth research and exploration within the areas of electromagnetics and electromagnetic control. According to the IEEE G-EMC journal, the research content of environmental electromagnetics includes: (1) research on electromagnetic detection methods and electromagnetic interference prevention technologies, as well as the use of related instruments, meters, and equipment; (2) research on the sensitivity, attenuation, and compatibility technologies of electronic equipment; and (3) research on several interference sources and their characteristics. For example, White's work... This research focuses on the physical mechanisms and analytical methods of power pollution; measurement techniques, information processing, and monitoring systems for power pollution; the mechanisms, scope, and tolerance of its hazards; control, elimination, or suppression measures; and the theoretical and technical issues arising therefrom. The rudiments of this new discipline can already be seen in some recently published works. In recent times, research on power pollution has focused on the following aspects: 1. Establishing new pollution source models and improving their accuracy, with a focus on models under non-ideal conditions and stochastic models. 2. Improving the accuracy of power supply system models. A prominent characteristic of power pollution compared to other types of pollution is its close relationship with the power grid. The propagation of distorted waves and transient waves on the power grid depends on grid parameters, which can suppress or amplify distortion. Models consider resistance and inductance under different frequency currents, long-line models considering standing wave effects, and three-phase network models with asymmetrical layouts. 3. Network analysis, based on network theory, is effectively applied to harmonic analysis, combining frequency and time domain analysis, evolving from Fourier analysis to wavelet analysis, and integrating deterministic and stochastic analysis. Optimization methods are more effectively employed in design and calculation. 4. Significant progress has been made in measurement methods and technologies, with the development of new measuring instruments and monitoring systems, moving towards multi-functionality and intelligence. 5. Based on research into pollution impacts and equipment tolerance, a series of limiting standards and management regulations have been formulated and improved, and their implementation is being organized. For example, based on the "Interim Provisions on Harmonic Management of Power Systems," my country has successively formulated national standards such as "Power Quality Public Power Grid Harmonics" and "Power Quality Standards: Allowable Voltage Fluctuations and Flicker." 6. In pollution control, while improving power quality and continuing to refine existing control methods and means, new devices have been developed and some new ideas have been proposed. For example, automatic tuning filters based on closed-loop control, parallel filters used in conjunction with series filters, and hybrid compensation devices combining passive and active filters can achieve the effect of leveraging strengths and compensating for weaknesses, combining waveform compensation with phase compensation; combining conventional static var compensators (SVCs), filters with dynamic power compensation filters (DPFs) can achieve optimal control of nonlinear, non-periodic complex distortions, resulting in a power factor of 1, minimum resonance, stable voltage, and optimal load. This integrates pollution control with grid operation control. 7. New theories, concepts, and definitions related to power pollution and power quality have developed, and some issues and terms have been discussed. Basic conclusions : Power pollution has emerged and become increasingly serious with the development of modern power. Power pollution is closely related to the system and is essentially a power quality problem, involving a wide range of aspects and possessing unique complexity, making it difficult to understand and control. With technological advancements, power pollution can also be effectively controlled and will ultimately be integrated with grid operation control. The theoretical development and practice of power pollution have gradually formed its own theoretical system and engineering practice, thus forming a new interdisciplinary field—power environmental engineering.
