The company is responsible for project design, equipment production, installation and commissioning, and completes the project within 6 months to realize one-time power transmission.
Technological breakthroughs:
● Product design review function: Automatically record relevant telemeasuring and telesignaling data in case of important events in the substation, and intuitively trace back after the event, which is convenient for operation and maintenance or technical personnel to find out problems;
● Substation voltage and reactive power regulation function: Through the monitoring system, set the voltage or reactive power target value, automatically control the reactive power compensation equipment, and adjust the tap of the main transformer to realize the automatic voltage and reactive power control;
● With the integrative analysis function of the monitoring software of the integrated automation system and through communication with the microcomputer protection device of each line, various electrical data and signals of each line and system when small current grounding faults occur can be combined for judgment, and the faulty line can be identified by reasonable methods to provide effective alarm information for the operators of the hydropower station or factory in time and act as a basis for preventing further development of grounding faults。

JSH provides project design, equipment production, installation, and commissioning services, and complete construction within six months, realizing successful power delivery in just one time.

Technology Breakthroughs:

Incident recall function: automatically record relevant telemetry and telecommunication data for intuitive traceability and convenient for O&M and technicians to determine the problem

Voltage reactive power adjustment function: set the target value of voltage or reactive power via the monitoring system, automatically control the reactive power compensation equipment, and adjust the main transformer tap, realizing the automatic control of voltage and reactive power

Integration of analytical functions: make use of integrated automation system monitoring software to provide operators with effective alarm information in time, giving a basis for the further development of ground fault prevention
