The power generation systems in alternating current, require a fast and accurate speed control. An ELC (Electronic Load Controller) is an automatic control system, designed to maintain accurate and stable the nominal rotational speed of the turbine-generator group, so to deliver electrical power with high quality in voltage and frequency.

Governor type and description
The governor should be a PID full-programmable (digital) electro-hydraulic governor in parallel. It adopts the programmable controller body to measure frequency, with frequency-power adjustment, speed adjustment, automatic tracking of power system frequency, self-diagnosis, and stability. Features. The governor uses a proportional servo valve or a digital valve, which has a high resistance to oil pollution. When working in oil with a 60渭m filter, it will not cause malfunction due to being stuck. The governor should be able to start and stop at a distance, control output and stop at an accident; and provide a communication interface, including hardware and software, in accordance with the technical requirements of the computer monitoring system.China Speed Governor
