Design Optimization - Define Load Profiles

A load profile defines the electrical usage of a home. You may define multiple load profiles for various types and sizes of homes. Load profile information is stored in the MMENG_LOADPROFILES table.

To create a load profile or modify an existing profile, open the MMENG_LOADPROFILES table and create a new row or modify an existing row. The fields in this table are defined below.

The MMENG_LOADPROFILES table catalogs the various load profiles to be considered for the design. Each row provides a description of a typical consumer load type for the utility. Administrators can configure various types of loads here. Each load profile can specify a coincidence curve that allows the optimizer to account for diversified load demand.

Default Building Floor Area: An administrator can set this value in the DEFAULT_KNOWN_FLOOR_AREA field.

Field

Description

LP_NAME

A unique name associated with the load profile.

LP_DISPLAY_NAME

The load profile name displayed in the Design Optimization user interface.

FLOOR_AREA_RATIO

This is the percentage by which the parcel area is multiplied to estimate a Known Floor Area when one isn't provided by the user.

DEFAULT_KNOWN_FLOOR_AREA

Default value of the building floor area. If you wish to set a default building floor area value, enter it in this field. Users will be able to override the default in the Load Profile Parameters section (Load Profile Settings task).

PEAK_KVA_AREA

Maximum electric load demand per floor area.

AVG_KVA_AREA

Average electric load demand per floor area.

PEAK_POWERFACTOR

Maximum power factor per floor area.

AVG_POWERFACTOR

Average power factor per floor area.

INRUSH_KVA

Instantaneous load required upon a motor start.

MOTORSTART_POWERFACTOR

Power factor required upon a motor start. This value is used to calculate flicker.

COINCIDENCE_CURVE_ID

Percentage of the sum of the load for all connected service points. Expand the field to view two columns. The first is the number of service points displayed as [#]. The second column is the percentage of the total load for those service points.

NUMBER_OF_PHASES

Number of phases for the service. Valid values are 1 or 3.
