1. Arrangement of burden at the power plan generator unit Operational Power Plan Generator Unit Electrical Power Plant Engineering 1 st Class Semester 2

2. Governing of payload at generator unit Generator Without Burden ( Zero) If generator axis turned around with speed synchronize and rotor given field current of If, hence tension of E0 E0 will induce at the stator yoke bobbin equal to : E0 E0 = cnΦ where : c = konstanta n = synchronize rotation F = fluxs Operation AC generator without burden, its armature current will zero ( IaIa = 0) so that terminal voltage of Vt = Va = Vo. Because is big of the induction ggl represent function of magnet flux, hence induction ggl can be formulated: Ea = f ( F), meaning arrangement of field current until certain condition will result ggl induce without burden in a state of saturation

3. Generator with Burden Three kinds of nature of burden if attributed to generator, that is : burden of resistive, inductive load, and capacitive load. Effect of this burden will have an effect on to burden tension and power factor

4. Relation and characteristic of generator without burden.

5. If generator burden have the character of resistive result degradation of small tension relative with power factor is the equal to one. If generator burden have the character of happened inductive [of] degradation of big enough tension with situated behind power factor ( lagging). On the contrary, If generator burden have the character of capacitive will happened increase of big enough tension with power factor precede ( leading) Load characteristic

6. Relation between voltage without burden ( E 0 ) with voltage of burden ( V 1 ) referred by voltage regulation, expressed as follows : Voltage Regulation ( Eo = V 1 / V ) x 100%

7. After rotary generator at a speed of normal and in a condition goodness, hence ready to conducted by encumbering at the operating system. Encumbering at the generator can have the character of resistive, capacitive and also inductive depended from burden type accepted by generator

8. Exciter System At the time of generator attributed to burden will cause tension output of generator will go down, because yielded magnetic field of constant lasing current relative. To be constant generator tension, hence there must be the make-up of proportional reinforcement current with increase of burden

9. Interconnection System Interconnection system is electric power system which consist of some electrics center and mains watchman station ( GI) which interconnected ( connective the other ) passing transmission channel and serve burden exist in all main station ( GI).

10. A Interconnection system which consist of 4 Center Electrics and 7 main stations ( GI) with Transmission Voltage 50 kV

11. Isolation system is system which only having a just electrics center and there no one inter connection between electrics center and also there is no link with public network ( inter connection property of PLN). System which isolated for example there are in a industry processing of wood residing in the forest or at the drilling of offshore oil which reside in the sea. At system which Isolated used PLTD or of PLTG. At System which isolated, division of burden only conducted among generating units in one electrics center so that there are no problem of channeling of energy between electrics center as does at the system of inter connection. PLN also have many system which isolated in the form of a PLTD with distribution network which limited to one countryside, that is new area experience of electrification.
