unbalance_percent |
float |
unbalance in percent defined as the ratio of V0 and V1 according to IEC 62749 |
The power flow bus results are defined as:
net.res_bus_est
The state estimation results are put into net.res_bus_est with the same definition as in net.res_bus.

vm_pu |
float |
voltage magnitude [p.u] |
va_degree |
float |
voltage angle [degree] |
p_mw |
float |
resulting active power demand [MW] |
q_mvar |
float |
resulting reactive power demand [Mvar] |
Note
Bus power values are given in the consumer system. Therefore a bus with positive p_mw value consumes power while a bus with negative active power supplies power.
