I'm having issues with powerflow in Simpower systems

Hi everyone, I am having some very basic questions in the simulation of a simple 3-bus radial system. This system is shown in Fig. 1 below

My question is why is the power at 'load bus 2' not equal to the value set in the three phase RLC load. My parameters for RLC load are Presistive = 10kW and Pind=1kW. But if I carry out simulation and use the PQ measuring function block, the value I calculate is 8877 kW and inductive power is 1621 kVar. I am using Phasor mode to run the simulation.
Would appreciate any feedback.
Aditya

PS I have attached the model here for anyone who would like to take a look. For the model, please run R=1440, X=1440.

This is an effort to clean up Matlab answers. I apologize as this answer is too late to be useful to the asker:
Unfortunately, I can only speculate, as some paramters were not provided in the model that was shared. It would seem that your transimision line paramters are too high. If I put realistic parameters for R and X, I get almost identifcal results at both busses. However, if I put very large values in for R and X, I can start to get the same results that you have.
