Methods for Performing Load Flow Study

A load flow calculation is used to evaluate the state of a system for a given load and generation distribution. As the network distribution will vary noticeably during different time periods, it may be required to perform several load flow solutions pertaining to peak, light and average loading conditions.

These solutions will be used to define either optimal operating modes for normal conditions or how the system will respond to abnormal conditions.The solutions to these equations are then evaluated using iterative techniques like:

Newton Raphson

Jacobian Matrix

Gauss-Seidel method

Newton raphson method

Jacobiab matrix

Gauss shiedel method

Our Approach

We also perform Power Flow study on the latest version of ETAP. In doing this, our efficient power systems engineers builds a network of nodes interconnected by admittances (impedances). In defining nodes in a software model, we consider the following input data

BUS DATA

For PQ buses (Load Buses)

Real power (generation and demand)

Reactive power (generation and demand)

For slack bus (Swing Bus)

Voltage magnitude (usually 1 per unit)

Voltage Angle (specified to be zero)

Real power (demand),

Reactive power (demand)

For PV buses (Generator Buses):

Real power (generation and demand)

Reactive power (demand)

Voltage magnitude

LINE DATA

Transmission lines

Resistance

Reactance

Capacitance (can be negligible)

Transformers

Winding resistances on low and high voltage side

Leakage reactance on low and high voltage side

Magnetization reactance & Iron loss admittance

Load Flow Analysis

To begin the Voltage Stability Analysis of a power system, computation of the complex voltages at all the buses is essential. After this, power flows from a bus and the power flowing in all the transmission lines are to calculate. A computational tool for this purpose is Load Flow Analysis. This analysis helps compute the steady state voltage magnitudes at all the buses, for a particular load condition. Load flow is mainly used in planning studies, for designing a new network or expansion of an existing one. The next step would be to compare the calculated values of power flows and voltage with the steady state device limits, to estimate the health of the network.
