The principal of a natural gas generator system is to use hydrocarbon gases that occur naturally underground, such as methane, as fuel in a generator to produce energy for electrical devices. One can buy such generators from 'Electric Generators Direct'.

If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
its a technical
technical approach in information system has to do with computability
It depends what type of system you are talking about.If it is technical system it only has hardaware and software.Examples of technical systems are:Radio,TV,PC... If you are talking about Socio-Technical System that it has hardware,software,process and procedures.Most importantly Socio-Technical systems have a knowladge of why they are used and have humans as a operators. For example book publishing system is a socio-technical sstem, govermental system is socio-technical system...
Generators that run on natural gas are connected to gas lines provided by your local utility company. Have your generator installed by a reputable, licensed installation professional. He or she will insure that the generator is properly installed and is inspected and deemed safe by your local building safety inspector. This type of generator will operate automatically when your power goes out to supply you with emergency power. Have the system checked for safety every year by a qualified servicing company.
Too much load for the generator, the generator began to under speed / overspeed, the governor / part of the generator went into failure, the generator capability was not up to the requirements placed by the system (needing to push out/pull in too many VARs), etc. there are many reasons for a generator to drop a load. Because a load dropped, this does not infer that the generator was the cause either (fault on the system, system instability limits reached, system protection tripped - non-generator related protection).
Bell System Technical Journal was created in 1922.
Bell System Technical Journal ended in 1983.
Reverse power flow into a generator can occur during synchronization if the generator is spinning too slowly, or the voltage phase angle is lagging relative to the power system. If the generator is spinning too slowly, power from the system is used by the generator to increase its' speed. If the phase angle is lagging, an initial spike of power will flow into the generator to force it into sync with the system. Typically generator's will match system frequency very closesly, and force the phase angle to leading slightly between the generator and the system. When synchronized, an extra bump of power will flow out while the generator is torqued into phase with the system. This will avoid tripping any reverse power devices.
Business system are the logical system which raise on technical system and these are created in SLD. Technical system are physical system which has system technical information like system server name, host name etc. Business services are used for B2B scenario and these are not created in SLD. These are used when we have not third party system information.
