Full Load Hour
Full Load hour is a measure of the degree of utilisation of a technical system. Full load hours refer to the time for which a plant would have to be operated at nominal power in order to convert the same amount of electrical work as the plant has actually converted within a defined period of time, during which breaks in operation or partial load operation can also occur. The figure usually refers to a period of one calendar year and is mainly applied to power plants. The annual utilisation rate or capacity factor derived from the number of full-load hours is the relative full-load utilisation in a year, i.e. the number of full-load hours divided by 8760 hours, the number of hours in a year with 365 days. Description Typically technical plants are not constantly operated at full load, but depending on various factors (see below) the system can be under a partial load. The total work (physics), work converted by the plant in a year is therefore less than the maximum possible work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Year
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
