In simulink i want to simulate a simple power system network with just a stand alone synchronous generator ,a transmission line and a nonlinear load so that harmonics can be generated by the electrical load.I can simulate synchronous generator and transmission line with linear loads BUT DON'T KNOW HOW TO CREATE POWER HARMONICS IN SIMULINK

it seems that by the time difference between the question posted and your remark, if Bikram had wanted to hang any finding here it would have been done time ago, which means that either didn't find anything or found something worth not being shared in a public forum, don't you agree Gautam?

unfortunatley, this answer is too late for the asker, but it is a very common question so here is a response:
The easiest way to inject harmonics is to use a controlled current source (you can also use a controlled voltage source). Then you can inject any additional signal on top of the existing model. Otherwise you need to build a realistic source or load with harmonics which is typically more work, but is useful if you don't know what harmonics the load/source would inject. For these cases you need to include switching effects to get the appropriate harmonics.
This is a useful block for adding random noise: https://www.mathworks.com/help/simulink/slref/bandlimitedwhitenoise.html
