Simulating a changing load in an electrical power system

I have to simulate a transmission line in an electrical power system. How do I simulate a load if this load is raised every minute?

@nur hadi: I answer questions here in this forum. Sending emails will not increase my motivation to reply.
I have no experiences with Simulink. The lack of answers is a strong indication for an incomplete question. Without the necessary details, a meaningful reply is impossible.

I'am using SimPowerSystems in simulink matlab 2010a. I try simulate a constant power load at a bus growing per minutes. Power rate with 0.932 inductive power factor..

It sounds like you are using SimPowerSystems. If your load is a resistive load, you may want to try the approach described here to model a variable resistor. You can then use standard Simulink blocks to construct the signal of resistor value as a function of time. If it's not a resistive load, then you need to provide more details.
HTH,

yes mr arnaud, I'am using SimPowerSystems in simulink matlab 2010a. I try simulate a constant power load at a bus growing per minutes. Power rate with 0.932 inductive power factor.. can you help me to simulate this..

Have you had a look at the demos provided in SimPowerSystems? There are quite a few of them and one of them may be a good starting point for your application.

Hi Nur/Arnaud,
I have tried downloading both 2010a/b and 2009a/b version of matlab and none of them seems to have simpowersystems. I got this folder from my professor and saved it under the matlab folder and still doesn't help. Can you give me some advice?
Thank you in advance
Best, Yuling

Where did you download MATLAB from? SimPowerSystems is an add-on to Simulink, which is itself an add-on to MATLAB. So you need to purchase Simulink and SimPowerSystems as well as MATLAB.

Transmission lines are groups of wires, called conductors, that carry electric power from making plant life to the substations that deliver power to customers. At a generating plant, electric power is “stepped up” to numerous thousand volts by a transformer and brought to the transmission line.
