Solution Detail & Operating Principle
Practical Challenge
Under current grid connection regulations, solar PV systems—particularly large-scale power projects—are strictly required to undergo remote monitoring and load dispatch by the electricity authority (EVN). Without standardized hardware capable of compliant signal transmission and reception, power plants cannot pass grid connection acceptance testing, posing severe risks to national grid stability and facing potential power generation suspension.
Product Solution
The RMCS device serves as an intermediate communication gateway, fundamentally resolving technical barriers between solar PV stations and the grid operator's management infrastructure. By standardizing communication protocols, the product ensures seamless transmission of operational data and execution of power regulation commands, guaranteeing full grid compliance while maintaining legal and stable power generation.
Operating Principle
At the site, the device continuously measures and aggregates active power, reactive power, voltage, current, and frequency parameters from inverters and billing meters. Following signal processing and data packetization, these metrics are transmitted to EVN’s SCADA system via telecommunication channels using the standard IEC 60870-5-104 protocol. Conversely, during grid oversupply or instability, the RMCS receives control dispatch orders from EVN and automatically executes grid disconnection or inverter power curtailment within seconds.
Safety Design & Integration Capabilities
Housed in a rugged industrial steel cabinet, the product comes equipped with electromagnetic interference (EMI) protection and surge protection devices (SPD). It offers highly flexible integration, operating seamlessly in parallel with site-level internal monitoring systems (EMS/SCADA) without interfering with EVN’s primary communication link. Transmitted data is strictly encrypted, ensuring top-tier cybersecurity protection.
Practical Applications
The RMCS device is a vital technical component for commercial and industrial (C&I) rooftop solar installations, manufacturing facilities, and utility-scale grid-connected solar farms. Installing this device is a strict prerequisite for project developers to complete Commercial Operation Date (COD) procedures and maintain safe, compliant connection to the national power grid.
