Factors Influencing

Nowadays, direct media use in learning energy is rarely found. Therefore, the authors intended to design a mini micro-hydro power plant (MHPP) in order to give direct experiences to students. This study generally aims to develop a mini MHPP consisting of equipment design, component selection, and the MHPP assembly. A test on discharge, heights, and produced power is then conducted. The data acquired are then analyzed in terms of either Pteotirik or Preal power using a predetermined equation. An analysis to the factors influencing the P values is then carried out. The power input of  resulted from the water discharge management is 35.64 mW, while that of the power output  is 9,61 mW. The efficiency of the MHPP set is by 26.96% which is considered quite low due to such factors as turbine blades, penstock pipes, generators, and the shift from water potential energy to other types of energies which is inevitable. It is expected that the developed mini MHPP is applicable as practicum learning media giving a lot of such learning experiences to students as to identify how hydroelectric power plant is, how the water energy shifts into electric energy, how high the electricity produced is, and to analyze factors influencing how high and low the electricity produced by a power plant.

Increasing Demand

Energy consumption in Indonesia is increasing every year, the fulfillment of the energy needed must be overcome. Energy is something that is really needed by anyone, from humans or animals to be able to do something or work. This energy is also abstract, its existence can be felt, but it is difficult to prove. Electricity needs of the community today are a basic need. Electricity usage is almost 24 hours nonstop. To cope with the increasing demand for electricity, it is necessary to utilize natural resources that can be used as new energy resources. The floating hydro power plant simulator is a hydroelectric power plant that utilizes the flow of water from a pump to drive a waterwheel, a device designed to make it easier for students to learn basic electrical engineering and fluid mechanics. The purpose of this design is to design and build a floating hydro power plant and test the tool. The design method used the VDI 2222 method approach, which includes planning, conceptualizing, designing, finishing. The results of the design were according to the method used, namely in the form of a waterwheel simulator design for power plants. The estimated production process time for the manufacture of a floating hydro simulator for cutting 3.9 hours; process of gurdi 3.08 hours; lathe process 1.3 hours; 1.58 hours assembly process; finishing process 2.75 hours = 1.2 days (1 day = 8 hours). The total cost of making the machine was Rp. 2.605,740.00. The driven pulley test results in 65.4 rpm and the driven pulley produced 304 rpm and the output was 12.3 volts.

The hydrological regimes of surface water bodies, as a rule, are unsteady. However, accounting for the non-stationarity substantially complicates the hydrodynamic calculations. Because of this, the scenario approach is traditionally used in the calculations. Characteristic scenarios are set with constant hydrological characteristics throughout the time covered in the calculations. This approach is fully justified if the characteristic time of the change in water flow rate is much longer than the calculation time. However, nowadays, tasks are becoming more and more urgent when accounting for flow variability during calculation period becomes crucial. First of all, such a problem arises when assessing the effect of non-stationary water discharge through hydroelectric power plant dams on the hydrodynamic regime of both the upper and lower pools of the reservoir. In the present paper, the effect of the intraday variability of the Kamskaya Hydroelectric Power Plant (Kamskaya HEPP) operation on the peculiarities of the hydrodynamic regimes of the near-dam part of the upper pool of the Kama reservoir is described. The importance of the problem is determined by the location of the main drinking water intake of Perm city and one of the largest thermal power plants (TPP) in Europe, Permskaya TPP, in this part of the reservoir. This TPP uses a direct-flow cooling system from the Kama reservoir, which is very sensitive to the peculiarities of the hydrodynamic regime of the reservoir. The computational experiments based on the combined hydrodynamic models in 2D/3D formulations have shown that the intraday oscillations of the discharge flow rate through the dam of the HEPP have a very significant effect on the hydrodynamic regime of the reservoir in the vicinity of the Permskaya TPP; therefore, these effects must be taken into account when minimizing the risks of thermal effluents entering the intake channel of the Permskaya TPP.

This article considers issues of regulating the non-metallic building materials extraction in the lower reaches of large hydroelectric power plants. The problem is quite urgent when a large city is located in the lower tail of a hydroelectric power plant and the process of extraction of non-metallic building materials is superimposed on the rather complicated issues of interaction with other water users. The article employs the technique of mutual overlap of bathymetric surveys for the previous periods combined with the analysis of the declared volumes of extraction of non-metallic building materials. A simulating hydrodynamic model of the Votkinsk reservoir has been made, with taking into account the data on the fractional composition of bottom sediments. During the development of the model, we used the software products HEC-RAS v.4.1 and SMS v.11.1. The use of onedimensional and two-dimensional models made it possible to simplify calculations without significant loss of accuracy of calculations. Based on these models, a deformation of the bed was calculated under the standard conditions of the hydrological regime of the Kama and Votkinsk reservoirs. The outcome of the work is recommendations on the allocation of sites in the lower tail of the Kamskaya HPP, where the extraction of non-metallic building materials is not recommended, the areas where production is possible subject to a number of conditions and restrictions concerning the volume of production and areas where production is possible without restrictions.

Set Up

Built in 1923, the Ubrug Hydro Power Plant in Sukabumi was set up with an installed power of 5,94 MW on 1st unit and 2nd unit and 6,48 MW on the 3rd unit resulting in sum total of 18,36 MW. However, at present, the actual total power only generates 15,045 MW, a smaller number than its initial capacity, due to the lack of water discharge. Based on the measurement data, the load of the generator has experienced a decrease of power in normal field operation with a peak load of 9,5 MW and the lowest of 6 MW. On daily operations, only 2 generators are being operated, leaving the 3rd generator unoperated. This is due to the aging hydroelectric power plant on the location and the transition of forest functions in the upstream area, that serves as water absorption, to settlements of residents, and industrial estates. The other and the most salient cause is the waste carried by the Cicatih River coming along with the flow of water in the conduit.

In the Ecuadorian electrical market, several sugar plants, which significantly participate in the local electricity market, are producing their own energy and commercializing the surplus to the electrical market. This study evaluates the integral use of the sugar cane bagasse for productive process on a Cogeneration Power Plant in an Ecuadorian Sugar Company [8]. The electrical generation based on biomass requires a great initial investment. The cost is around US$ 800/kW installed, twice the US$ 400/kW initial investment of conventional thermoelectric power plant and almost equal to the US$ 1,000/kW initial cost of hydroelectric power plant [5]. A thermoeconomic study was carried out on the production of electricity and the sales of the surplus of 27 MWe average produced by the power plant. An operational analysis was made using instantaneous values from the estimated curves of demand and generation of electricity. From the results, it was concluded that the generated electricity costs are 0.0443 US$/kWh, while the costs of the electricity from Fossil Power Plants (burning fuel oil, diesel fuel and natural gas) are in the range 0.03–0.15 US$/kWh and from Hydroelectric Plants are about 0.02 US$/kWh. Cogeneration power plants burning sugar cane bagasse could contribute to the mitigation of climatic change. This specific case study shows the reduction of the prospective emissions of greenhouse gases, around 55,188 ton of CO2 equivalent yearly for this cogeneration power plant.

The paper presents the analysis of different types of impact the hydroelectric power plants’ reservoirs could make on the environment. Hydroelectric power plants (HPP) produce ecologically safe energy and correspond to the modern striving for sustainability because they are operated on renewable energy sources. At the same time they can provoke various potential dangers for the environment. The objective of the investigation is to demonstrate the interrelation between the type and structure of a hydroelectric power plant and the way its reservoir may impact on the nature surrounding the plant. These effects may be direct and indirect, positive and negative and vary from insignificant that can be easily fixed to those that are irreversible and catastrophic. The latter should be taken into account during the design of HPP.
