A Smarter ‘Smart-Meter’ with Embedded Programmable Logic Controller (PLC)

SATEC’s trademark direct-digital-controller within metering hardware incorporates a Programmable Logic Controller (PLC) serving a breadth of applications, defining what a ‘Smart Meter’ really is.

Why use a PLC in a meter?

Days of analogue instruments are fading, as is the use of ‘pulse only electrical meters’, or to the lesser extent, real-time-meters without internal memory and an internal clock. The evolution of multi-function electrical meter sees a wide gap in technology by vendors.

A traditional Programmable Logic Controller (PLC) can perform repetitive tasks reliably at low costs. By incorporating a PLC within an electrical meter, the real understanding of ‘what a Smart-Meter’ is can finally be realised.

Traditional control systems, such as a Building Management System (BMS) or Supervisory Control and Data Acquisition (SCADA) platforms have tended to perform monitoring and control tasks for energy management applications.

The use of a PLC within a Smart-Meter is proven to improve communication bandwidth, lower processor scan-time and improve code efficiency and effectiveness by optimising throughput.

A Meter for Engineers & Automation Professionals

BMS, PLC and SCADA generally performs most metering measurement and monitoring solutions. The rise of Energy Management Systems (EMS) is improving electrical metering systems due to several factors, particularly since electrical measurements and monitoring applications can be so vast in their respective applications.

eXpertpower | Solar PV Billing: An Integrated Architecture for Metering & Monitoring Solutions, A How To Guide For Improving Financial ROI & ROA

10796272 - solar energy panels in the setting sun
The increase use of Solar Photovoltaic (PV) systems demand a reliable electricity metering, monitoring and billing platform. SATEC’s Integrated Architecture provides a future-proofing solution, improves awareness of asset monitoring and repeatability metrics and solves revenue recovery reliability.

Setting the Billing Scene

Due to changes by the Australia Government’s National Measurement Institute (NMI), electrical metering for trade measurement, or billing, has become more complex. NMI Pattern Approved electricity meters are required for this application.

Working beyond invoicing for Energy (kWh) Consumption only, complex tariffs and applications must be solved. For instance, Time of Use (TOU) tariffs are becoming more common – these are generally ‘Peak/Off-Peak/Shoulder’ type requirements, or time periods during a 24-hour period whereby electrical networks see more or less usage from consumers.

Step Tariffs, or Inclining Block Tariffs, see rates charged for energy consumption different based on the use – e.g. First ‘<100 kWh’ charged at $00.20 and next ‘>100kWh’ charged at ‘$00.15’. Maximum Demand application work towards penalties or rewards for lessening power demand during certain periods, usually the ‘Peak’ time in TOU arena. Moving on from this, TOU Maximum Demand or Seasonal TOU are further complex billing applications future trade measurement professional must consider.

Metering Choices – Which one is for me?

The challenge is choosing between low cost electrical metering solutions and investing in Advanced Smart-Meters incorporating features and benefits commonly misunderstood.

Ensuring your meters are future compliant

Ensuring Electricity Smart Meters are Future Compliant

Electricity meters come in many forms. Understanding features and capabilities, as well as the requirements of an application, can ensure that today’s meter will meet tomorrow’s requirements.
There are many electricity metering options available today, with a range of features and capabilities. Many low-cost meters lack the functionality to ensure these devices will remain useful in the future. Accuracy, sampling rate and the electrical parameters measured can vary greatly from meter to meter, but more complex capabilities are where the future truly lies.

Smart Features

Tomorrow’s meters will need to encompass time of use (TOU) tariff functions, demand capabilities, communications for automatic meter reading (AMR), regulatory approvals, reading import and export of power, data logging capabilities, real-time clock (RTC), disconnect/reconnect capability, read and write in registers for remote control, as well as reprogramming and analysis of data for forensic investigation. Ensuring ‘energy smart’ meters are feature rich means now that future needs and market or regulatory changes will be met, reducing the likelihood of meter churn and overall lifecycle costs.
Applications such as solar energy generation may require metering to have four-quadrant measurement. In addition, interval metering with 15 or 30 minute data logging with date/time stamping is essential in today’s world, while gross and net metering require smart devices with the appropriate four-quadrant measurement functionality. Interval meters record energy or other electrical measurements at 15, 30 or 60 minutes intervals, or other intervals of time, providing date/time stamp of recorded data. Electricity and energy meters that incorporate event logs can provide additional information and date/time stamping for analysis in the event of problems such as voltage outages or reprogramming by unauthorised personnel.

Water and Gas

Not just electricity the expansion of additional energy readings for cold and hot water, gas and greywater monitoring can be an integral part of smart meters which incorporate pulse inputs. Pulses from water and gas meters can be sent to the smart meter, using pulse data logging, which can in turn be forwarded to billing systems and/ or building management systems (BMS) and other third-party software AMR solutions.

Accuracy Standards

Improved measurement standards, such as Class 0.5S accuracy to AS/IEC62053-22, have led to increased accuracy performance in smart metering without any major cost impact. Class 1.0 accuracy meters are widely accepted in the market. However, advances in standards coupled with new technology has provided for enhanced measurement with Class 0.5S, particularly at low loads and other electrical conditions.

Demand Capabilities

Energy Meters measure and record consumption based on kilowatt hours (kWh) in addition consumers may be charged on their demand period which could be measured in either kilowatts (Kw) or kVA {total of real power (Kw) and reactive power (Kvar) } demand structures will vary widely, but it is important your smart meter supports demand calculations.

Real Time Clock (RTC)

Having a clock (RTC) on board Energy meters is an important ingredient for functions as tariffs, demand issues, event logs, and data logging profiling which can provide sequence of date/time stamping.
Smart Energy meters have RTC, but clock specifications can vary. Ensure RTC are battery backed to ensure date/time stamp is not lost in the event of power loss. Some RTC loose date/time and have to be reset on the event of a power loss. Others may retain date/time stamp for up to 3 days using a capacitor.
RTC with battery backup should retain data for a period of up to 12 months or more, in addition the battery ageing life should be good for upwards of 10 years.

Space Savings

Advances in technology have improved the space-to-design ratio performance of smart meters. Reduced meter design space additionally reduces required panel space, while ensuring that operational and performance specifications are not compromised. Space is a premium in embedded networks, in both new installations and in existing buildings where retrofits or upgrades are required. Providing space savings using advanced smart metering designs can provide space savings upwards of 90%, when compared with typical ‘bottom up connect’ utility meters. This reduces the triple bottom line and provides savings across the board; from the architect to the builder or developer and the electrical contractor.

Sustainability Support

Smart meters that incorporate algorithms to profile energy usage showing daily, weekly, monthly and quarterly readings reduces the burden of the BMS or any third party software solution to calculate this format in the software. This function provides electricity, water and gas usage information in an easy-to-read format and ensures data is presented in a way that supports the reporting for sustainability rating tools and schemes including Green Star and NABERS, without the need for dedicated software.

Improved Communications

Advanced communications capability provides further benefits, allowing the meter to be read locally or remotely. Initially, the use of RS232 protocol provided only a 1:1 ratio of a master/slave relationship and the use of RS485 improved this to a ratio of 1:32. These topologies provide only limited communication, however, as software connections are restricted to a single master polling the downstream nodes or devices. Using Ethernet TCP/IP, as found in smart metering, provides multiple TCP socket support and therefore has the added advantage of providing flexible ‘multiple’ relationship configurations. As we move into the age of Internet of Things (IoT), smart meters are increasingly connected directly to the internet and the addition of an application programming interface (API) ensures interoperability via third-party software applications. As the NBN is rolled out across Australia, smart metering connectivity is inherently NBN-ready, or easily connected to the internet via ADSL-2, 3G or 4G, and data access is available to the end user without the restrictions traditionally associated with proprietary data.

Advanced Assurance

Trade billing measurement in Australia must comply with the National Measurement Institute of Australia (NMI) M6-1 standard, which provides assurance to the end user that the meter will continue to operate and function under varying metrology conditions, thus ensuring repeatability with accuracy standards. When considering the available options in smart energy metering, ensuring that the vendor has the required technical knowledge and can offer ready support should always be factored in, as should the warranty period on offer and the proposed warranty on accuracy performance.
