jaotusvõrgust

Jaotusvõrgustik, or distribution network, is a critical component of any power system, responsible for delivering electricity from the transmission network to end-users. It operates at medium voltage levels, typically ranging from 1 kV to 35 kV, and is designed to efficiently distribute power to various types of consumers, including residential, commercial, and industrial customers.

The primary function of a distribution network is to ensure reliable and continuous power supply to end-users. This is achieved through a combination of overhead lines, underground cables, and transformers that step down the voltage from the transmission level to the distribution level. The network is designed to be resilient and capable of withstanding various fault conditions, such as short circuits and overloads, to minimize power interruptions.

Distribution networks can be categorized into radial, ring, and mesh topologies. Radial networks are the simplest and most common, with power flowing in one direction from a central substation to the end-users. Ring networks provide an additional path for power to flow, enhancing reliability. Mesh networks offer the highest level of redundancy, with multiple paths for power to reach end-users, ensuring maximum reliability and fault tolerance.

The management and operation of distribution networks are crucial for maintaining power quality and system stability. This involves monitoring and controlling various parameters, such as voltage, current, and power factor, to ensure that the network operates within acceptable limits. Advanced technologies, such as smart meters and automated control systems, are increasingly being integrated into distribution networks to enhance their efficiency, reliability, and resilience.

In summary, jaotusvõrgustik plays a vital role in the power delivery system, ensuring that electricity reaches end-users reliably and efficiently. Its design, operation, and management are essential for maintaining the overall performance and stability of the power system.
