This chapter explores how the lean quality principles and green initiatives are applied in capital project equipment installation of electric substations and line rehabilitation from the initial feasibility studies to the plant-in-service phase. Equipment installation process predicaments induce cost overruns and unnecessary extended electrical outages as well as extraneous strain on the bulk transmission system. Demand side management issues are best mitigated through astute planning of the power supply resources, load curtailment initiatives, and transmission flow contingency schemes.

The Impact

When the high electricity demand growth is not matched by growth in generating sufficient capacity, deficit cannot be avoided. In Sumatera, power outages of up to 6 hours per day are part of the power crisis experienced. To date, deficits experienced by Sumatera require better management strategy and operation of electric power systems, taking into account the security system, reliability and customer service. This paper briefly discusses the impact of rolling blackouts on the community's economy and proposed demand-side management strategies as short term measure to overcome the power supply deficit in Sumatera. From the analysis, electricity savings in household equipment can save energy consumption by 98.79 MW at peak load and 97.55 MW for off peak load time.

Main Components

As an exploratory study for NMR experiments in the future 20 MW Nijmegen high field magnet laboratory, the possibilities of field stabilization and field gradient compensation in a 25 T hybrid magnet in the present installation were evaluated. High frequency field fluctuations from the power supply can be compensated to better than 10-3 ppm in the 10 Hz-10 kHz range using a computer controlled feedback system. Field mapping by 2H magnetic resonance using a homebuilt device not only showed that there are substantial axial but also strong radial field gradients. It can be shown that for any cylindrical multicoil Bitter magnet the main components of these gradients can be compensated with simple ferromagnetic inserts. In this way we achieved a linewidth under 5 ppm in 1 mm3 without further shimming or optimization. The low frequency drift of the field due to instabilities of the present power supply and the effects of temperature fluctuations of the coil are determined by simultaneous acquisition of an in-situ deuterium reference signal together with the signal of interest. This allows for a full compensation of the field fluctuations by deconvolution techniques. We will report preliminary NMR results on solid27 Al samples in fields up to 25 T.

Successful Solution

The liberalization of the electricity market aims at the most complete repletion of consumer needs for electricity and quality power supply, which requires the adaptive management of an energy using both by demand side and by the electricity producers – power plants. The successful solution of this task provides, in particular, for using the effective methods and reliable means for the formation of the informational support for the tasks of managing the power generation and delivery on the power plants in order to ensure conforming in real time the market power bids to current demand side asks. The article proposes a methodology, describes the implemented tools and analyzes the experience of managing the power generation and delivery on the cogeneration power plant based on the information which formed by the automated system for control, metering and energy management in the conditions of functioning of the liberalized electricity market of Ukraine.

Transformer 3 of Pesanggaran Substation obtains additional power plants with a maximum power of 60 MW. Power generation is used to supply the load of feeders in Substation of Pesanggaran and also channeled to 150 kV transmission system at Substation of Pesanggaran through Transformator 3 to Substation of Nusa Dua to assist power supply at Nusa Dua Substation. If there is a feeders interruption in the Substation of Pesanggaran which causes the load of feeders to be disconnected, then the power from the generator that is flowed to the 150 kV system increases. Thus the Transformer 3 works heavier, resulting in the current and temperature of the transformer also increased. Increased temperatures in the transformer for long periods can result in damage and reduced lifetime of the transformer. From the problems then calculation of current and working time OGS and OCR as the Transformer 3 safety system. The result of calculation of OGS setting of phase1 is 1600 A with setting work time of 2 seconds, phase 2 is 1700 A with setting working time of 1,5 seconds and stage 3 of 1800 A with setting work time of 1 second. The OGS relay characteristic is definite. For OCR at 150 kV side, the current setting is 277 A and setting time is 1.36 seconds, while OCR setting at 20 kV side is obtained by setting current of 2078.4 A and setting time of 1.18 seconds with OCR Relay characteristic used is inverse.

Electric utilities over the domain affected with ecological issues associated with standard fossil fuel-established plants are examining more within the potentiality of interposing energy sources type of plants into the system as an alternative. Integration of Demand Side Management (DSM) and Supply Side Management (SSM) is required in a rational power system planning that implies concurrent deliberation of both qualitative and quantitative problems like costs, fuel mix, and reliability of power supply. This chapter examines the economic and environmental ability of power supplies initiation into an existing peak deficit power system, incorporating both DSM and SSM plans. The Generation Expansion Planning (GEP) study is carried out in the power system for the period of 24 years planning horizon.
