Hydroelectric power plants capture the kinetic energy of flowing water from a river or reservoir and convert it into electrical energy. These power plants are generally located in hilly areas where a dam can be constructed to form a reservoir. Water from the reservoir flows through penstocks and turbines, using the force of gravity and water pressure to turn the turbine blades. This kinetic energy is then converted into electrical energy by an attached generator. The electricity is stepped up in voltage by transformers and distributed via power lines to customers. Hydroelectric power is a renewable source of energy and provides the additional benefits of flood control, water storage, and irrigation.

Hydroelectric Power Plant ppt for electrical engineeringsudiptomahato2345
Hydroelectric power plants convert the potential energy of water stored in reservoirs into electrical energy. The main components are:
- A reservoir that stores water higher than the turbine
- A dam that holds back the water and allows it to flow through gates
- A penstock that channels water down to spin the turbine blades
- A turbine whose rotation is converted by a generator into electricity
While renewable, hydroelectric plants have environmental impacts such as disrupted ecosystems and flooding of land.
1) Hydroelectric power plants utilize the kinetic energy of flowing water to generate electricity. Water turns turbines which spin generators to produce electricity.
2) There are several types of hydroelectric turbines suited for different water head and flow conditions including Pelton, Francis, and Kaplan turbines. Pelton turbines work best for high head applications while Francis and Kaplan are used for lower heads and higher flows.
3) The key components of a hydroelectric power plant include an intake, penstock, turbine, generator, and tailrace. Water is diverted from a source through the intake and penstock before passing through the turbine which spins the generator to produce electricity which is then transmitted through power lines.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
