Understanding Climographs: A Guide to Climate Analysis

Classified in Other subjects

Written at on English with a size of 2.27 KB.

The graphic is a Climograph, a double entry graph that registers the average monthly temperatures through a red line for the scale of degrees centigrade (ºC) on the right; and the total average monthly precipitation by a bars graph in mm* in the scale on the left. According to the usual conventions, both scales are in a 2:1 ratio**, which allows to visualize easier the drier months.

The yearly average annual temperature is ………….. The average monthly temperature belongs to the month of …………….., with approximately ……….. ºC. Such data indicates that, the graphic’s clima is located in the Northern hemisphere, also with a hot/warm summer. The coldest month is ……… with ……….. ºC, which means a mild summer. According...

Automatic Voltage Control and Generation Control in Power Systems

Classified in Other subjects

Written at on English with a size of 1.76 KB.

Automatic Voltage Control

Basically consists of a main exciter field which excites the alternator field to control the output voltage. The exciter field is automatically controlled through an error equal to V reference - Vt. When the output voltage is higher than the required value, the BT is measured by a potential transformer and fed back to the input so that the error V reference - Vt is applied to the exciting field. This ensures that the generator output voltage is maintained at the desired level.

Components:

  • Potential Transformer: Provides a sample of terminal voltage
  • Differentiating Device: Gives actuating error e = V ref - Vt
  • Error Amplifier: Amplifies the error signal
  • SCR Power Amp: Transfer Function = (ke / 1 + TeS)

Automatic Generation

Major Components of a Master Budget

A master budget can be divided into operating and financial budgets:

  • Operating budgets describe the income-generating activities of a firm: sales, production, and finished goods inventories. The ultimate outcome of the operating budgets is a pro forma or budgeted income statement.
  • Financial budgets detail the inflows and outflows of cash and the overall financial position. Planned cash inflows and outflows appear in the cash budget. The expected financial position at the end of the budget period is shown in a budgeted, or pro forma, balance sheet.

Behavioral Dimension of Budgeting
