## Description

The Governor Type 1 block models a model IEEEG1 steam turbine-governor model IEEEG1.

This block allows the modeling of cross-compound units and it has two sets of turbine fractions:

**LP Fraction, K_2**,**LP Fraction, K_4**,**LP Fraction, K_6**,**LP Fraction, K_8**for low-pressure (LP).**HP Fraction, K_1**,**HP Fraction, K_3**,**HP Fraction, K_5**,**HP Fraction, K_7**for high-pressure (HP).

You can switch between continuous and discrete implementations of the block by using the
**Sample time (-1 for inherited)** parameter. To configure the
governor for continuous time, set the **Sample time (-1 for
inherited)** property to `0`

. To configure the governor
for discrete time, set the **Sample time (-1 for inherited)** property
to a positive, nonzero value, or to `-1`

to inherit the sample time
from an upstream block.

This diagram illustrates the overall structure of the block:
