Core Functions
Metering Functions:
✓Measuring Active and Reactive energy, Import and Export energy, Reactive four-quadrant energy, Instantaneous data (voltage/Current/Power/PF/Angle...);
✓Multi TOU Tariffs and Multi Step tariffs, tariffs can be updated from the system;
✓High Anti-tamper: Detect of meter cover open, terminal cover open, current reverse, module cover open, cabinet door open, etc.
✓Storing mass data such as billing data, daily data, load profile etc.
✓Event logs such as grid quality logs, tampering logs, control logs, communications logs etc.
✓Multi load control mode, Local and remote load control, Relay malfunction self-check;
✓Metering firmware upgrade via local and remote communication;
Data Collecting Functions:
✓Scheduled & on-demand meter reading, including energy, grid quality data, load profile, billing, instantaneous data, event, alarm, tamper, etc.
✓Scheduled & on-demand metering cabinet monitor, including Cabinet Temperature, relay/valve status, etc.
✓Concurrent task processing mechanism to ensure the reliability of the collection process with multi-task, multi-thread, multi-connection and data packing methods;
✓Load balance working mechanism to ensure the availability of network resources;
✓Transmission resuming at breakpoints mechanism used to ensure data collection integrity after exceptions occurred;
✓Complement mechanism for abnormal data, which is used to ensure data integrity after the emergence of abnormal data;
Communication Functions:
✓Multi open and interoperable communication protocol and self-adaption to match the correct protocol. Such as DLMS (TCPIP), DLMS (HDLC), DLMS (Gateway), Q/GDW 1376.1, etc.;
✓Multi reliable and fast wired and wireless FAN communication way and modules, such as Fiber Optic/Ethernet/4G/3G/2G/Private LTE according to the site;
✓Multi resisting and flexible wired and wireless NAN communication way and modules, such as LORA/RF/MBUS/RS485;
✓Automatic registration, automatic network, self-configured, self-healing;
✓Communication bases on authentication, identification, encryption and right control;
Vending Functions:
✓Supports existing STS/CTS standards for prepaid vending;
✓Supports the security, module (TSM250 and TSM500);
✓Supports STS600-4-2 key management specification which includes rollover bit, new encryption algorithms and remote key loading: AES algorithm (FIPS 197), ECC (FIPS 186-3), SHA-256 & SHA384 hash algorithm (ISO 10118/FIPS 180-4), HMAC (ISO9797-2/FIPS 198-1), STA (IEC62055-41), TDES and DES for legacy compatibility;
✓Distributed vending management and supports 3rd Party vending channels;
✓Concurrent vending management;
✓Vending analysis, vending query, vending report, etc.
Data Anslysis Functions:
✓Line loss analysis includes technical energy loss and Non-technical energy loss.
✓Consumption analysis base on the quartered, hourly, daily, monthly, annually meter energy consumption, then analyze the consumer's habits of energy consumption and forecast consumer electricity usage. And as the key data of power dispatching.
✓Grid quality analysis base on the load profile and event logs. Analyze the period configurable load profile data to capture the minimum, maximum and average instantaneous data such as voltage/current/power...Analyze the random grid event logs to alarm the over voltage, under voltage, sag, swell, short/long power off, imbalance, THD...
✓Vending analysis base on the total, area, pos and specific consumer vending data, then analyze the consumer's purchases habits, special attention to the long time no purchase action and make effective revenue projections.
