The primary frequency modulation system refers to the centralized control of the distributed, independent and adjustable secondary system by a central control station through the communication network to realize the automatic adjustment of the frequency. It is a frequency adjustment scheme for the power system to ensure the stable operation of the power system.
A primary FM system usually consists of the following parts:
1.Central control station: responsible for receiving and sending control signals, centralized control of each secondary system.
2.Communication network: used to transmit control signals and data information, and send the instructions of the central control station to each secondary system.
3.Secondary system: includes a variety of adjustable equipment, such as generators, inverters, regulating valves, etc., and adjusts the frequency according to the instructions of the central control station.
4.Sensors and actuators: used to monitor the operating status of the power system and execute control commands.
The advantages of the primary FM system include:
1.Centralized control: Centralized control of the power system is realized through the central control station, which is convenient for management and maintenance.
2.Fast response: The primary frequency modulation system can quickly respond to changes in the power system and maintain frequency stability.
3.High efficiency and energy saving: Reduce power loss and improve energy efficiency by optimizing the operation mode of the equipment.
4.Analysis: Support decision-making through the analysis of power system data and the analysis of power system data.
It should be noted that the primary frequency modulation system also has some limitations, such as high requirements for the communication network, and the need to ensure the reliability and stability of the communication. In addition, for some special circumstances (such as large-scale power outages or natural disasters, etc.), the primary frequency modulation system may not work normally, and other emergency measures need to be taken to ensure the stable operation of the power system.
