Final Report Summary - DSOT300-125S (development and manufacturing of programmable electrical load and advanced PSM for electrical energy management testing in flight demo)

Executive Summary:
Today electrical system equipment are designed as “add-on” philosophy, they can draw electrical power from generators up to over load without any control of this request. Distribution system is transparent to this behaviour and it’s made by hardware devices providing wiring fault only in order to avoid a wiring escalation in case of wire fault.
Generators are capable of 150% and 200% of nominal power for 5 minutes and 5 sec respectively. To meet these requirements generator are over-sized, anyway a long lasting overload request will be faced by shedding not flight safe essential landing load. This policy is called load managment

The trend of “all-electrical” aircraft and green constraints calls for deep change in load management philosophy, the equipment will be useful during flight testing of EPC and flight demo.
The current proposal is aligned to the new calls for greening and fully useful to develop a new generation Electrical power centre able to manage power and loads efficiently.
Dana srl successfully proposed to develop a new Programmable Resistive Electrical Load with an Advanced Power Supply Module, having a 25 years experience on electrical load manufacturing, ensuring excellent reliability and easy to use GUI.
This equipment was named “DSOT300-125S” and was ensure fast response to input voltage transient ensuring optimum performances even testing an EPC in voltage chopping mode.
Special requests of qualification tests were fully satisfied, and the need for speed of loading the EPC has been ensured by a new analogue and digital redesign using solid state resistors specifically designed for this proposal.
The equipment has low temperature drift less than 0.1%.

Project Context and Objectives:
Electronic load SREL is an adjustable load capable through remote command to change the current sink. In fact, Electronic load SREL can simulate a resitor and its power range is from 0 W to 20 kW.
To change the power input of SREL there are three way: TTL command, PWM control and analog input. Each commands have a different effect on the load.
Through TTL command, the user can select betwen two load: 1 kW or/and 2kW.
The SREL is provided of 2 input PWM. The first change the power from 0 W to 3 kW. Second inpunt can adjust the power from 0 kW to 4 kW. The user can control both input PWM simultaneously. The sweep from minumim to maximum power is selectable in slow or fast mode.
Through analog input 0÷10 Vdc, the user can increase of 100 W for step the power from 0 W to 10 kW.
All selectable powers ensure a fast esponse to input voltage.
Temperature drift is less than 0.1 %.

Potential Impact:
The performed test on new generation EPC needs of electrical load with high performances and speed quality ensured on this project.
The load was tested for flight demo too, this impact on all JTI partners and members of on board commissioning and validation staff.
DANA is confident about the future develop and good relationship of JTI partners about further performances improvements and develop.
A excellent impact is expected about the APSM and SREL joint which allow to simulate new generation EPC having new loading management philosophy and voltage chopping mode which is not supported from any electronic load yet.
As mentioned above equipment performa all APSM functionalities ensuring an easy test of all external power sources
