Frequency regulation (Frequency Regulation) is an essential task in power systems, aimed at maintaining the stability of grid frequency. The frequency of a power system typically needs to be kept within a specific range, such as 50 Hz or 60 Hz, to ensure the proper operation of all electrical equipment. Here are several common methods of frequency regulation:1. Primary Frequency ControlPrinciple: Primary frequency control is achieved by automatically adjusting the output power of generating unit

Determining the input/output impedance of circuits with transistors or other active components is an important step to understand the performance and matching characteristics of the circuit. Here are some common methods and techniques for determining these impedances:1. Analytical MethodsInput ImpedanceSmall-Signal Model: Use the small-signal model of the transistor (such as common-emitter, common-base, common-collector, etc.) to analyze the input impedance.Common-Emitter Amplifier: The input im
