This paper describes how to test a power plant excitation system by using a small-scale generator. The tests are part of applied research titled "Localization of Static Excitation System of Hydro Generators in Iran". Considering the high risk of various tests on the under-development excitation system for a power generator, a small-scale generator...
This paper presents a technique for on-line estimation of synchronous generator parameters, using an excitation disturbance. To illustrate and verify the proposed algorithm, some excitation disturbance tests are conducted on an actual hydro generator. Machine response to the applied disturbance is processed by proposed technique using artificial ne...

Unbalanced load is one of the fashionable problems in distribution systems, which has great unfavorable effects such as unbalancing in three phase voltages, increase of energy losses and occupation of feeder capacity. There are two main sources of unbalanced load, the first ununifored distribution of the single phase customers and the other, their...
Pollution flashover is the major problem for operation of distribution network in IRAN, particularly in region close to Persian Gulf and Oman Sea. Conventional methods for measuring site pollution severities have formed the subject of many studies
According to DIN50019, the coastal districts of Persian Gulf are classified as extreme hygrothermal climatic zone. unusually high saturation vapor pressure up to 53mbar observed in this zone, justify this marking, as such air humidity phenomena are unique in the free atmosphere of the earth and are absolute extremes. intensive night falls of dew, w...
High voltage insulators have to be used as insulating supporters in various environments in polluted area. The electrical performance of insulators will be degraded. The polluted insulators will have over withstand voltage, flashover can occur easily when the air becomes wet by humidity or fog, which affects on the reliability of the power systems....
Power system security refers to the degree of risk in a system's ability to survive probable disturbances (contingencies) without interruption to customer service. Dynamic Security Assessment (DSA) is the analysis required to determine whether or not a power system can meet specified reliability and security criteria in both transient and steady-state time frames for all credible contingencies. With the increase in the share of Variable Renewable Energy (VRE) plants in the power generation portfolio, the system stability and dynamic security are vulnerable to changes.
