Abstract
In the modern times of industry where hydraulic are of use, all the motors run on their nominal workload, where the pumps are constant. The given flow is regulated with the help of valves which chokes the flow. From an energy perspective this contributes to a great amount of energy losses, where the demand can be much lower than the supply. We can observe from today’s society that the energy costs rise frequently, which have contributed to more attention and greater consideration to this factor. The motors are controlled by a drive system which is built on the master/slave principle, this means that the master commands the slave. The problem with today’s system is that if a master disappears, then the whole system will collapse. This has... (More)
In the modern times of industry where hydraulic are of use, all the motors run on their nominal workload, where the pumps are constant. The given flow is regulated with the help of valves which chokes the flow. From an energy perspective this contributes to a great amount of energy losses, where the demand can be much lower than the supply. We can observe from today’s society that the energy costs rise frequently, which have contributed to more attention and greater consideration to this factor. The motors are controlled by a drive system which is built on the master/slave principle, this means that the master commands the slave. The problem with today’s system is that if a master disappears, then the whole system will collapse. This has created an urge to develop a system where all the drivers can be a potential master or slave. In this thesis our main focus is on the analyzing and research parts of possible solutions to both a stable, independent system and a smart energy optimization, where our main goal is to achieve an energy efficient work dividing between the motors as possible. The thesis is made at Bosch Rexroth in their offices. We will present our analyzing of the solution methods in this report and give both theoretical and practical examples, to prove the motivation behind our decisions, comment advantages and disadvantages to what these solutions contributes with. Notice that all our solutions in the research part will not be included in the result, we will discuss this later in the discussion part. The drivers which are thought for use in this thesis are Bosch own and are named indradrive, it contains a PLC and a PID-regulator. It’s also thought that the implementation will be done in Bosch own software, Indraworks. The implementation will only occur if there is time available and will be a prototype for two asynchronous engines. (Less)
