Tarbela Dam

The World Bank Study," Water and Power Resources of West Pakistan" [1], is one of the most thorough-going and sophisticated of its type. In re¬reading it we have been struck by a curious argument related to the real benefits to be expected from the construction of the Tarbela dam. It was designed to produce electricity as well as to irrigate land and it was necessary to estimate the benefits that the electricity would confer. One way of doing this was to estimate the saving that would be made by using hydro-power instead of natural gas or imported fuel, for electricity generation. This meant that an appropriate set of prices had to be estimated for Pakistan's supply of natural gas. The way in which this was done was, to say the least, unusual. The relevant passage justi¬fying the approach adopted is as follows:

The renewable energy systems (RESs) are an attractive option to electrify the community as they are environment friendly, free of cost, and all-pervading. The efficiency of these energy systems is very low and can be improved by integrating them in parallel. In this paper, hydro (7.5 kW) and solar systems (10 kW) are taken as RESs and connected with the utility grid. Due to the intermittent nature of both the hydro and photovoltaic energy sources, utility grid is connected to the system for ensuring the continuous power flow. The hydro power generation system uses the self excited induction generator (SEIG) and converters. The AC/DC/AC converter is used as interface to connect the hydro turbine to the utility grid to adjust the generated voltage to the utility grid voltage. The solar generation system is the combination of PV array, boost converter, and solar inverter. The control of both the hydro and solar power plants is provided through the constant current controller. The analysis has been done to verify the existence of the proposed system. Results demonstrate that the proposed system is able to be put into service and can feed the community.

Characteristic Features

In this paper we investigate the possible penetration of combined-cycle plants in the Belgian electricity generation system after the Belgian Government has not considered as appropriate the construction of a next nuclear plant at the present time. First the characteristic features of the Belgian production capabilities are given. The share of gas turbines, turbojets and already existing combined-cycle plants and their operation modes are emphasized. Then, alternative options to nuclear energy are presented, i.e. repowering of existing plants and construction of new combined-cycle plants. The potentialities of gas turbines and CC plants as well as their future in Belgium are investigated. Finally we discuss the equipment plan for the Belgian generation system proposed by the management committee of the electrical plant operators. From the results of our research about repowering, gas turbines and new CC plants, we derive recommendations for the future production means in Belgium.
