Methods for Voltage Stability EnhancementRavi Anand
This document discusses various methods for enhancing voltage stability in power systems, including using lower power factor generators, capacitor banks, controlling transformer tap changers, undervoltage load shedding, coordination of protections and controls, control of network voltage and generator reactive output, use of FACTS devices, artificial neural networks, fuzzy logic, excitation control, booster transformers, phase shifting transformers, secondary voltage regulation, series capacitors, and must-run generation. It provides details on how each method can be implemented and their effectiveness.
This presentation begins with a discussion of the generator as a source feeding a very large remote system (the "single-machine infinite-bus" representation).

Ms. Tan Mei Wei joined Deloitte's Melaka Branch Office on February 11, 2008 as an audit assistant and left the company's employ on her own accord on March 13, 2009. This letter from Deloitte serves to certify Ms. Tan's employment dates with the company.
This document presents a project proposal for analyzing the transient stability of the Kenya power system incorporating geothermal power from the Menengai power station. The proposal provides background on geothermal power plants and their components. It discusses the problem statement around evaluating a power system's ability to withstand disturbances. The objectives are to analyze the transient stability of the system with more power injection and compare the stability of different synchronous machines. The methodology will use Dig SILENT software to simulate disturbances like faults, generation loss, and load changes to analyze active power, voltage magnitude, and rotor angle responses.
