Parameters can be adjusted externally by the web system! Introducing development examples in the EMS field.
We would like to introduce a case study of the development of an Energy Management System (EMS) that performs power factor control to address reverse power flow at wind power plants. Using process information (analog) such as line-to-line voltage, phase angle, generator output, and wind speed, we estimate system load and power generation output to perform power factor determination. After implementation, we can maximize generation efficiency by controlling output to prevent reverse power flow in self-consumption type generation facilities. 【Case Overview】 ■Industry: Power Generation ■Field: EMS ■Development Environment ・PLC: Hitachi Industrial Equipment Systems PLC (HX) ・Touch Panel: Web Visualization (on PC) ・Communication Method: Modbus/TCP (for peripheral devices) *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Introduction Effects】 ■ By implementing output control to prevent reverse flow in self-consumption type power generation equipment, the generation efficiency can be maximized. ■ By conducting future predictions based on wind conditions and internal load situations, output control can be performed in advance (gently) to extend equipment lifespan. ■ To respond to sudden load fluctuations, feedback control is implemented to prevent system downtime in advance. *For more details, please refer to the PDF document or feel free to contact us.
