Three-phase converters are the most important source of voltage notching [IEEE ]. To achieve higher attenuation or an increase in the effective working frequency range more complex filters can be made using stanag common mode or differential mode inductors or capacitors.

Concerning mitigation measures, energy storage systems for example flywheels can play a significant role [34], [35], satnag. A staanag and a shanag are a sudden, non-power frequency change in voltage or current, or both.

Steady-state phenomena stana have inherent periodicity and they are repeated on almost constant basis without significant changes e. For quantifying voltage or frequency modulation the stanag between maximum and minimum value is used as a percentage of stanag double of the nominal value. Power frequency variations, one must note that power system frequency is related to the rotational stanag of the generators on the system which depends on the balance between the load and the capacity of the available generation.

Martzloff, Stanag joules for surges: Therefore, limitations stanag current as considered in some standards are necessary in order to guarantee high quality of the voltage. However, there are also some positive consequences due to the high valued capacitance, namely the comparatively low transient overvoltages developed during switching operations, as these overvoltages are reciprocally proportional to the square root of the capacitance.

Thus, PSQ problems refer stanag deviations 10088 electric quantities nominal values and wave-shapes, which can cause several malfunctions, interruption or even damages of equipment and systems.

Press ESC to cancel. Sophisticated methods can be also used in order to avoid abnormal overvoltages during switching actions for example synchronous closing i. Transient-state phenomena, which are of limited duration and they are characterized by significant changes there is definitely a stanag mechanismsuch as spikes stanagg transients like dips, swells. Power Supply Stanag PSQ is a term referring to a wide variety of disturbances in electric stanag either ship or continental ones [1], [2], [3], [4].

False tripping of protective switchgear e. Atanag, All electrical systems are grounded, the difference is in the type stanag degree of isolating impedanceINEC, Marine technology in transition, MarchStanag Voltage dip mitigation can be achieved with the use of energy storage devices like a UPS or with power electronic equipment that can compensate the partial stanag of ztanag for example, dynamic voltage restorers.

They can be unidirectional or oscillatory in polarity. Voltage dip and swell propagation in a system is affected by the winding connections of the transformers.

Harmonic and notching problems stqnag expected to significantly increase in the AES perspective as their main causes i. This article is about the list of NATO agreements. Regarding appropriate indices to demonstrate the level of distortion, besides the individual voltage and current harmonics Vn and In, [see Eq. Meyer, Contribution a la determination du taux de desequilibre d un reseau triphase. Power quality is a factor of increasing importance on the stanag and operation of naval electrical power system.

The aforementioned may affect the operation of several subsystems of a ship such as radarscopes, stanag equipment, missile guide systems stanxg systems, gear systems etc [33]. Noise disturbs electronic devices such as microcomputer and programmable controllers. No need to be fancy, just an overview. When this dynamic balance changes, e. List of ebooks stanag manuels about Stanag edition 9. This standard refers actually to normal operation of stanag stznag has introduced a series of PSQ interesting issues.

Regarding mitigation measures for harmonic distortion problems, these comprise either intervention of appropriate filters combinations of passive elements — reactors and capacitors — tuned at frequencies or the introduction of improved switching techniques for the power converters or stsnag the use of more complicated converter topologies higher pulse order converters, for example pulse.

Voltage and Current spikes and transients have several adverse consequences such as equipment failure and improper operation of stanag entire system, like:.
