Four Detailed Implementation Plans for Standardization

Plan 1: Three-Tier Energy Consumption Data Collection for Factories/Industrial Parks (Mainstream for Commercial and Industrial Applications)

Topology

Multifunctional meter on the main incoming line (0.2S metering point) → Second-tier data collection terminals in workshops → Multi-circuit data collectors for equipment branches → Edge gateway → Energy cloud platform

Hardware Configuration

Feeder Cabinet: ADL4000 three-phase DIN-rail meter, open-and-close CT retrofit (no power outage required), 0.2S accuracy, harmonic and demand measurement

Workshop Feeder Circuits: Multi-channel data acquisition terminals (12-channel / 24-channel), open-core CTs for collecting sub-metered electricity consumption of motors, air conditioning, and lighting

Edge Gateway: 4 RS485 ports + dual Ethernet ports, Modbus-to-MQTT conversion for cloud transmission, local load-exceedance alarms triggering actions in the power distribution cabinet

Core Value

Accurately track electricity consumption across workshops and equipment, identify high-energy-consumption devices, optimize off-peak power usage, reduce base electricity charges, and meet dual energy consumption control requirements and ISO 50001 energy management system certification.

Solution 2: Distributed Integrated PV-Storage-Charging Data Collection (Residential / Commercial & Industrial PV Storage)

Data Collection Targets

PV inverters, energy storage PCS+BMS, charging stations, bidirectional meters at grid connection points, and facility load circuits

Key Technologies

Bidirectional Energy Metering: The gateway meter supports metering of both forward power consumption and reverse power fed back to the grid

Anti-Reverse Flow Collection Strategy: The gateway monitors reverse power in real time and automatically issues commands to reduce PV output or activate energy storage to absorb excess power

Coordinated Dispatching: During the day, PV power supplies the load, and excess power charges the energy storage system; during the evening peak, the energy storage system discharges to reduce grid peak load

Communication Solution

Inverters / BMS connect to the gateway via RS485 Modbus, then transmit data to the cloud via 4G or fiber optic; the Zynq solution enables long-distance transmission of power plant data to the monitoring center via fiber optic.

Solution 3: Low-Voltage Centralized Meter Reading for Distribution Network Substations (State Grid / Southern Grid Standardized)

Architecture

Substation concentrator (edge gateway) → HPLC power line carrier / RS485 → Residential smart meters → DL/T645 meter reading → IEC104 upload to power company master station

Functions

Automatic meter reading, frozen energy data collection, voltage monitoring, three-phase imbalance detection, electricity theft detection, line loss calculation, power outage reporting; supports batch management of millions of meters.

Solution 4: High-Precision Fault Waveform Recording and Acquisition at Substations (FPGA/Zynq High-Speed Solution)

Hardware

Zynq XC7Z045 data acquisition unit, 16-channel synchronous 16-bit ADC, GTH SerDes fiber-optic Aurora transmission to the control room

Capabilities

Millisecond-level transient waveform acquisition, harmonic analysis, short-circuit fault waveform recording, SOE events accurate to 1 ms; integrates with the IEC 61850 substation platform and complies with secondary security standards for power grids.
