The achievements of superconducting technology show new prospects for power systems. The superconducting generator with a capacity of 10,000 kilowatts has been put into trial operation and the development of superconducting generators with a capacity of 1 million kilowatts continues. Improvements in the properties of superconducting materials will make superconducting power transmission possible. Superconducting energy storage devices can be developed using superconducting coils. New power equipment such as power batteries and fuel cells have kilowatt-level products in the trial operation stage and are gradually entering industrial applications. These research topics have the potential to realize electrical energy storage and establish decentralized and independent power sources, thereby causing major changes in the power system.
Among all industrial sectors, the power system is the largest entity system with complex levels and strict real-time requirements. Whether it is system planning and basic construction or system operation and operation management, it has opened up a broad field for the application of systems engineering, information and control theories and technologies and promoted the development of these theories and technologies. Based on the characteristics of power systems, system engineering methods, including reliability analysis and various optimization methods, have been widely introduced in power system planning and design in the safety analysis and management of power system operations since the 1990s. The advancement of electronic technology, computer technology and information technology has brought power system monitoring and dispatching automation to a new stage and continues to raise new research topics theoretically and technically.
The power system is composed of power plants, substations, transmission lines, distribution systems and loads.
It is one of the most important and complex engineering systems in modern society.
The power network is composed of transformers, power lines and other equipment that transform, transmit and distribute electrical energy.
The power system is a system that includes the power part of the power plant (such as the boiler of the thermal power plant, the steam turbine of the thermal power plant, the reservoir of the hydroelectric power plant, the water turbine, and the reactor of the nuclear power plant, etc.) on the basis of the electric power system.
The total installed capacity refers to the sum of the rated active power of the actually installed generating units in the system, measured in kilowatts, megawatts, and gigawatts.
The annual power generation refers to the sum of the actual electric energy generated by all the generating units in the system throughout the year, measured in kilowatt hours, megawatt hours, and gigawatt hours.
The maximum load refers to the maximum value of the total active load of the power system within a specified time, measured in kilowatts, megawatts, and gigawatts.
The rated frequency is stipulated in accordance with national standards for all AC power systems in my country.
The highest voltage level refers to the rated voltage of the highest voltage level power line in the system.
The main structure of the power system includes power sources (hydropower stations, thermal power plants, nuclear power plants and other power plants) substations (boost substations, load center substations, etc.) transmission, distribution lines and load centers. Each power point is also connected to each other to realize the exchange and regulation of electric energy between different areas to improve the safety and economy of power supply. The network composed of transmission lines and substations is usually called a power network. The information and control system of the power system consists of various detection equipment, communication equipment, safety protection devices, automatic control devices, monitoring automation, and dispatching automation systems. The structure of the power system should ensure reasonable coordination of electric energy production and consumption based on advanced technical equipment and high economic benefits.
According to the installed capacity and power load in the power system, as well as the relative position of the power point and the load center, the power system often uses different voltage levels for power transmission (such as high-voltage power transmission or ultra-high voltage power transmission) to achieve the best technical and economic results. benefit. According to the characteristics of the current, the power transmission mode of the power system is also divided into AC power transmission and DC power transmission. AC transmission is the most widely used. DC power transmission uses DC power to transmit the electric energy generated by the alternator after rectification.
