Generaatorvastandvõrkudes

Generaatorvastandvõrkudes, commonly translated as generator internal resistance or synchronous machine resistance, refers to the electrical resistance inherent within the windings of an electric generator. This resistance is a physical property of the conductor material, typically copper, and its dimensions. When current flows through these windings, a portion of the electrical energy is converted into heat due to this resistance, leading to power loss.

The value of generaatorvastandvõrkudes is generally quite low, especially in large industrial generators, due to the use of thick conductors to minimize losses. However, it plays a crucial role in the operational characteristics of the generator. It affects the voltage regulation of the machine; as the load current increases, the voltage drop across the internal resistance also increases, causing the terminal voltage to decrease. This phenomenon is a key factor in determining how well a generator can maintain a stable output voltage under varying load conditions.

Furthermore, generaatorvastandvõrkudes contributes to the short-circuit current that a generator can produce. In the event of a short circuit, the internal resistance, along with the synchronous reactance, limits the magnitude of the fault current. Understanding and accounting for this resistance is essential for accurate generator modeling, protection system design, and power system stability analysis. While often considered alongside synchronous reactance, the resistive component is a distinct parameter influencing generator performance.
