[ID] Pada musim kemarau PLTA Koto Panjang pernah mengoperasikan satu unit turbin dan generator sehingga daya yang dihasilkan tidak maksimal. Pada musim yang sama PLTA ini juga pernah mengoperasikan tiga unit turbin dan generator namun hanya menghasilkan daya listrik  35 MW dengan prosentase  50 % yaitu  30,702 % dari daya maksimal pengoperasian tiga unit turbin dan generator. Tujuan dari penelitian ini adalah untuk mengetahui debit andalan PLTA Koto Panjang, optimalisasi yang dilakukan dalam mengoptimasi PLTA Koto Panjang, daya listrik yang dihasilkan dari hasil optimalisasi tersebut dan perbandingannya. Metode empiris Penman digunakan untuk menghitung nilai evaporasi. Debit andalan untuk debit outflow PLTA saat ini dan setelah dioptimalisasi dihitung menggunakan rumus daya listrik dan metode mass curve. Selanjutnya debit outflow PLTA yang telah didapatkan dianalisis di dalam tabel water balance menggunakan metode sequent peak analysis. Hasil yang didapatkan adalah debit andalan PLTA saat ini dan setelah dioptimalisasi yaitu 305,319 m3/det dan 384,465 m3/det dengan prosentase 51,995 % dan 39,235 %. Optimalisasi dilakukan dengan menyesuaikan debit outflow dengan volume air yang ada pada storage saat itu. Daya listrik setelah dioptimalisasi adalah sebesar 13.302,315 kWatt pada musim kering dan 143.551,645 kWatt pada musim hujan. Daya listrik yang dihasilkan PLTA saat ini adalah sebesar 13.302,315 kWatt pada musim kering dan 114.000 kWatt pada musim hujan. Sehingga daya listrik yang dihasilkan PLTA setelah dioptimalisasi mengalami kenaikan dari daya listrik sebelum dioptimalisasi sebesar 29.551,645 kWatt. Karena kenaikan daya melebihi kapasitas generator PLTA saat ini, maka terjadi penambahan 1 generator 30.000 kWatt atau 30 MW. [EN] In the dry season, Koto Panjang Hydroelectric Power Plant has operated one turbine and generator unit so the power produced is not optimal. In the same season, this hydropower plant has also operated three turbines and generators but only produces  35 MW of electricity by percentage  50% which is  30,702 % of the maximum power from operating three turbine and generator units. The purpose of this research is to determine the mainstay discharge of Koto Panjang Hydroelectric Power Plant, optimization will be used for Koto Panjang hydroelectric power plant, power can produce from its optimization and its comparison. The Penman empirical method was used to calculate the evaporation value. The mainstay discharge for hydropower plant outflow discharge at this time and after being optimized is calculated using the electrical power formula and the mass curve method. Furthermore, the hydroelectric power plant outflow discharge has obtained is analyzed in the water balance table using the sequent peak analysis method. The results obtained are the current mainstay discharge of hydroelectric power plant and after optimization, which are 305,319 m3/s and 384,465 m3/s with a percentage of 51,995% and 39,235%. Optimization is done by adjusting the outflow discharge to the volume of water in the storage at that time. The electric power after optimization is 13.302,315 kWatt in the dry season and 143.551,645 kWatt in the rainy season. The current electricity generated by hydroelectric power plant is 13.302,315 kWatt in the dry season and 114.000 kWatt in the rainy season. Therefore the electric power generated by hydroelectric power plant after optimization has increased from the electric power before it is optimized which is 29.551,645 kWatt. Because the increasing of the electric power exceeds the capacity of the current hydroelectric power plant generator, there is an addition 1 generator which is 30.000 kWatt or 30 MW.

Proper Operation

Trash racks are the first element mounted in inlet channels of hydraulic structures. Their primary task is to capture coarse pollutants flowing in the riverbed/river channel and protect water facilities downstream. With the use of these devices, it is possible to separate coarse suspended matter, branches carried with the current, floating plastic elements, etc., which undoubtedly contributes to a trouble-free flow through culverts or channels and prevents hydroelectric power plant turbines from failure. An important issue here is also to ensure the proper operation of trash racks, particularly in respect of hydraulic structures whose task is to convert water energy into electricity (hydropower plants). Proper operation of trash racks minimizes losses arising from obstructing the free flow of water through accumulated waste or, in the wintertime, through icing. Incorrect work in this area entails specific head losses, and consequently leads to economic harm. In the paper, the resistance values of trash racks were analyzed at small hydropower plants (SHPs) operating at low temperatures, determined under laboratory conditions, with the occurrence of frazil ice and ice. The results indicate that the added ice into the channel resulted in the formation of a cover in front of the trash racks with an average thickness of about 0.02 m. The accumulated ice increased the head losses up to 14%. The range of the ice cover depended on the weight added ice and reached 0.6 m in analyzed cases.

Presently, however, Hydroelectric is a source of power that can prove to be available to all, regardless of conditions such as weather. As history showed, a lot of development, as well as alterations, were made to this efficient supply of energy. Hydropower is a positive alternative energy source that nature provides, therefore, its effective usage is not prohibited. Although there are many disadvantages associated with the design and construction of a hydroelectric power plant, the advantageous features are even more enormous. This paper deals with construction and design aspects for the implementation of the small hydroelectric power station. The main parameters can be collected from the site. Then the turbine type and dimensions can be specified. The generator specifications,which is the main part in the system, for hydro-power stations can be obtained from the determination of turbine output power. These specifications involve mainly the rated power in KVA, the type of system, system frequency, the type of stator winding connection, rated load voltage, rated load current, load power factor, generator speed, method of the system cooling, and the generator type of excitation.
