At Appelton, Wisconcin the first water wheel generator was installed. Under Edison's patents several companies started functioning in USA. However, these companies could supply energy to small distances due to I2R power loss being excessive at low voltage distribution.
In , Wililiam Stanley invented the transformer. The invention of induction motor in by Nnikola Tesla caused dramatic change in electrical power consumption through AC replacing many DC motor loads. It is now an acknowledged fact that HV and EHV transmission alone can reduce substantially the losses and bulk power transmission is feasible at these voltages.
Nevertheless, it is also well established that HVDC is convenient and more economical from operation and control point of view under certain circumstances such as at distances of more than kms.
A detailed discussion of this aspect is not within the purview of this book. In India, two third of the electrical power generated is from coal based power stations. At the time of independence, the per capita consumption of electric 2 Operation and Control in Power Systems energy was 1.
It is now about 3 units while China's per capita consumption is about 6 units. Developed countries have per capita consumptions of as high as 8, units. This shows the great disparity that exists between the rich and the poor countries.
However, Indian Power Sector has undergone revolutionary changes. While in the installed capacity was at MW, today it has surpassed 1,00, MW. In India regional and national power grids are established to facilitate transfer of power within and across the regions with reliability, security and economy on sound commercial principles. The Power Grid Corporation was established in August and it started its commercial operations from It is one of the largest transmission utilities in the world.
Challenging jobs in operation and maintenance of the national demand which is expected to reach a peak value of MW by are undertaken by Power Grid Corporation. Power Grid is also engaged in activities such as unified load dispatch which facilitates close monitoring of grid with real time data for economic dispatch of power between the five regional grids and states. Manual computation of power flows isexrremely time consuming even for very simple networks.
In , AC network analyzer, an analog computer was devised. Most of the early system studies were performed on the network analyzer.
The Indian Power Grid System is divided into five regional grids. Likewise, other boards are formed. Each state has inter State and Inter Regional links. The stipulated system frequency in India is 50 Hz. Since, there is deficit of generation in the southern region, the operating frequency goes to States like, Maharastra, Madhyapradesh, and Orissa operate at 50 to 52 Hz. While, we have dealt with the frequency scenario, it is worthwhile, to look at the other performance index of electric power, the voltage profile.
Introduction 3 From the above, it can be seen that there is very heavy demand for electric power in this areas seriously compromising the power quality. While more generation is needed to be added continuously a thorough knowledge of various aspects involved in the study of power system operation and control is very essential for electric power engineers. This book is dedicated to this task in a manner that students of power engineering grasp the essential concepts involved in operation and control.
The system variables are continuously changing in both magnitude and number.
The system never reaches a steady state so as to permit any tests to be carried out on it, so that its dynamic behaviour can be ascertained. In practice, it requires both continuous and discrete controls. The spread of the power systems over vast geographical areas contributes to its vulnerability to environmental changes.
The system's dynamics extends over a broad band width ranging from micro seconds to several minutes. Planning operation and control of isolated or inter connected power systems present a large variety of challenging problems, the solution of which requires application of several mathematical techniques from various branches of it.
