Thesis Paper On Power Factor Improvement

A better understanding of these issues will enable public policy to be designed in a direction which improves energy security and efficiency.It is against this background that this study examined the impact of power factor improvement schemes on peak electricity demand.

One of the findings from the electricity energy audit studies was that energy efficiency in large industries in Uganda could be attained by installation of power factor correction (PFC) equipment such as capacitor banks.

Such power factor correction equipment could be installed as distributed PFC, group PFC, centralized PFC, combined PFC or automatic PFC depending on the underlying causes of the low-power factor in the electrical system.

Energy saving initiatives such as the power factor improvement scheme of ERT-2 project contribute significantly in mitigating and stabilizing peak or maximum demand of electrical network resources (Schneider Electric ).

In countries such as Uganda where electricity supply barely meets the system demand requirements, policymakers, regulators, system operators as well as distribution network operators are always wary of any likely surge in the maximum demand that may propagate system outages and hence jeopardize the quality of electricity supply.

Results suggest that power factor correction technology implemented among industries and commercial enterprises increased the power factor in these industries from an average of 0.68 to 0.95 and saved up to 8.04 MVA of demand as at the end of 2014.

Results further indicate that the implementation of the power factor correction scheme has reduced the growth rate and abated the variability of both total maximum/peak demand and domestic peak demand.

Finally, with the implementation of power factor correction scheme, there is a noticeable reduction in electricity consumption at peak time of use (TOU) and growth in consumption of electricity at nonpeak time TOU, which was not the case before the implementation of the scheme.).

At the production firm level, the benefits of energy efficiency include reduction in resource use, improved production and capacity utilization, and less operation and maintenance costs, which lead to improved productivity and competitiveness (International Energy Agency (IEA) ).

The ERT-2 project focusing on the power factor improvement scheme is implemented by the Private Sector Foundation Uganda (PSFU) under the Business Uganda Development Scheme (BUDS).

The target power to be saved under this initiative is 10.4 Mega-Volt Amperes (MVA) of demand and associated wasted energy.
