The frequent starting of large motors causes fluctuations in the line voltage. Frequent use of welding machines can also easily cause fluctuations in the line voltage. This is mainly due to
The power systems are heavily stressed due to theincreased loading and this leads to voltage stability problem. Voltage Stability can also be called as the “load stability”. A power system lacks the capability to transfer an infinite amount of electrical power to the load.
The main factor contributing to voltage instability is usually the voltage drop that occurs when active and reactive power flow through inductive reactance associated with the transmission network; this limits the capability of transmission network for power transfer.
Restored loads increase the stress on the high voltage network causing more voltage reduction. A rundown situation causing voltage instability occurs when load dynamics attempts to restore power consumption beyond the capability of the transmission system and the connected generation. Voltage instability does not always occur in its pure form.
Instabilitythat may result occurs in the form of a progressive fall or rise of voltage of some buses. The possible outcome of voltage instability is loss of load in the area where voltages reach unacceptably low values or a loss of integrity of the power system. How Voltage Instability occurred?
Catastrophic decrease in voltage leads to loss of stability in large interconnected power system causing blackout. In this paper we will discuss the various causes and the prevention methods for power system collapse.
The system may originally be prone to voltage problems because of the electrical distance between its generation and load centers (dotted line). The voltage and reactive power support from the neighbouring systems is assumed to be marginal.
