The reason for this tech talk is to discuss how DC Power supplySupply and harmonicsHarmonics filter can affect the efficiencyEfficiency of your product, in cost of AC electrical power per ton of product you get out. Also, AC grid stability, which can affect other departments in the plant and even the neighbors. And lastly, we will discuss AC grid compliance, and how different systems can greatly cause an effect on it. To understand how this all affects the cost of equipmentEquipment, the electric bill, and compliance and penalties, we will cover the following key areas. The beginning of IEEE 519 AC grid compliance, rectifier typographies, the restrictions, and limitations from the standards. The advancements in power technologyTechnology, and the advancements in HarmonicHarmonics filtering and mitigation. The cost impacts related to harmonicsHarmonics, on not only the equipmentEquipment that produces the product, but all the other equipmentEquipment in the plant that is receiving the line harmonicsHarmonics from the equipmentEquipment. Also, the substation transformer costs and potential damage. Plant-wide power harmonicsHarmonics filters are an advantage for long-term protection for all electrical equipmentEquipment. It is also important to have the proper power factorPower Factor (PF) and harmonicHarmonics monitoring equipmentEquipment. This is necessary for those preventing higher electric bills, increasing strain the power grid. This prevents running equipmentEquipment above their ratings, advanced aging of equipmentEquipment, or even damages power equipmentEquipment. The key is that with the proper designDesign and monitoring of a DC power system and harmonic filterHarmonic filters, to meet the latest standard of IEEE519 and to not incur an electric penalty.
