BL118 Node-RED Edge Gateway for Power Meter Data Collection

Modbus is one of the oldest and most widely implemented industrial communication protocols. Originally designed by Modicon in 1979 for use with their programmable logic controllers (PLCs), Modbus has stood the test of time due to its simplicity, reliability, and ease of use. At its core, Modbus is a serial communication protocol, but it has evolved to include variants like Modbus RTU (Remote Terminal Unit), Modbus ASCII, and Modbus TCP/IP, which uses Ethernet as the transport layer. Lets check the some of measure points. #Modbus RTU #Modbus TCP/IP.

⚡🤖 The Day Copper Wires Lost Their Throne in Substations 🤖⚡ I still remember walking into an old substation years ago — rows of copper cables everywhere, tangled like veins, carrying every signal from CTs, VTs, breakers, and relays. It worked… but it was slow, rigid, and expensive. Then came IEC 61850 — and with it, the era of Digital Substations. Suddenly: 🔹 Copper wires → replaced by fiber optics 🔹 Bulky relays → replaced by smart IEDs 🔹 Manual checks → replaced by automation & real-time monitoring 🔹 Local signals → became instant GOOSE messages & MMS communication The result? ✅ 80% fewer copper cables ✅ 40% faster installation ✅ Safer, smarter, and future-proof substations But here’s the part that still amazes me 👇 Digital substations aren’t just about efficiency. They’re about trust. Trust that the grid will self-heal, respond instantly, and keep entire cities running — without anyone even noticing. To me, IEC 61850 wasn’t just a new standard. It was the moment substations stopped being “dumb boxes of steel” … and became intelligent guardians of the grid. 💡 Question for the community: Do you think in 10 years, we’ll even remember conventional substations — or will everything be digital? #IEC61850 #DigitalSubstations #PowerSystems #ElectricalEngineering #SmartGrid #GridReliability #EnergyInfrastructure #FutureOfEnergy

🔌 How Do Modern Substations Trip Breakers in Less Than 4 Milliseconds? (No SCADA involved!) ⚡ Imagine this: A fault happens → a relay senses it → a circuit breaker trips — all before you can blink! And here’s the magic: there’s no hardwired signal, no polling, no CPU lag. It’s all thanks to IEC 61850 GOOSE Messaging. 🚀 GOOSE Messaging Made Simple GOOSE = Generic Object-Oriented Substation Event Here’s what happens step by step: 1️⃣ An IED detects a fault and instantly creates a GOOSE message 2️⃣ This message is multicasted over the Ethernet LAN 3️⃣ Subscribed IEDs receive it immediately — e.g., tripping a breaker 4️⃣ The entire process completes in just 3–4 milliseconds! ✅ No IP addresses. No polling delays. Just ultra-fast, event-driven action. 🔍 Why Engineers Love GOOSE -⚡ Ultra-Fast: Sub-millisecond delivery of protection signals - 🌐 Multicast: One signal, multiple devices respond - 🔧 Flexible: Configurable via SCL files - 🔁 Reliable: Supports PRP/HSR redundancy - 🤖 Smart & Autonomous: Event-driven, no master/slave logic 🔧 Common Use Cases - Breaker failure detection & interlocks - Busbar & transformer differential tripping - Load shedding automation - Fast transfer tripping between bays - Recloser & blocking logic 🎯 Quick Checklist Before Deploying GOOSE ✅ Define GOOSE control blocks & datasets ✅ Use VLANs & QoS for network prioritization ✅ Assign proper multicast MACs ✅ Time-sync all IEDs ✅ Simulate, test, and verify 💡 As substations go digital, protection must go beyond copper wires. GOOSE messaging isn’t just faster — it’s smarter, leaner, and scalable. #SubstationAutomation #IEC61850 #GOOSEMessaging #SmartGrid #ElectricalEngineering #PowerSystems #ProtectionSystems #EnergyAutomation #DigitalSubstation #IndustrialAutomation #PowerEngineering #SmartSubstations #ElectricalProtection #EnergyTech #GridReliability #AutomationEngineering #HighVoltage #ElectricalDesign #EngineeringInnovation #TechInEnergy

🔌 Seamless Communication Between Protection Relays – Harnessing GOOSE One of the fascinating parts of working in power system protection is seeing how quickly and reliably devices communicate in a modern substation. Recently, I was working on setting up GOOSE messaging between two IEDs (Intelligent Electronic Devices). Unlike traditional hardwired signals, GOOSE allows relays to exchange information within milliseconds over Ethernet, enabling: ✅ Faster trip signals and logic sharing ✅ Reduced copper wiring across panels ✅ Flexible interlocking and scheme modification ✅ Improved system reliability in critical fault scenarios What excites me is how technologies like these are shaping the digital substations of the future—moving us from hardwired connections to interoperable, IEC 61850-based communication architectures. #PowerSystemProtection #RelayEngineering #IEC61850 #GOOSE #DigitalSubstation #ElectricalEngineering
