Description: A Discrete 3-Phase ProgrammableSource block is used to generate a 1 pu, 15 degrees positive sequence voltage. At t = 0.05 s the positive sequence voltage is increased to 1.5 pu. At t = 0.1 s an unbalance is introduced by adding a 0.3 pu negative sequence component with a phase of -30 degrees.
The magnitude and phase of the positive-sequence component is evaluated in two diiferent ways: 1) Sequence calculation of phasors using Fourier analysis and
2) abc to dq0 transformation.
Math Function and Trigonometric Function blocks are used to evaluate the magnitude and phase of the positive sequence from the d and q components:
V1 = sqrt(Vd^2 + Vq^2) , Phi1 = atan(Vq/Vd))

Description: The sensor nodes of a wireless grain depot
surveillance system are deployed in crystal grids, which provide
lot of valid position information. To avoid the energy
consumption unbalance of the single hop routing model adopted
by LEACH protocol, a novel hybrid routing model is proposed
in this paper. Multi-hop routing is introduced into the distant
field nodes through right angle transferring of approximate
equivalence consumption path. And the average energy
consumption is used as a threshold of selecting intermediate
transferring nodes to minimize total variance of node s energy
consumption, so that balance the whole network. Simulations
show that the hybrid model eliminates hot spots within cluster
and prolong the lifetime ofWSN. -The sensor nodes of a wireless grain depot
