Background

In the traditional billing system process, files were used to maintain the database which was done manually. There are many challenges facing the utilities regarding the billing process. like, data manipulation, managing customer information, costly billing process, several system installations (integration).  the aim of developing a billing system is to computerize the work performed in electricity.

System Overview

Dealing and managing utility customer information can be complicated and time-consuming, utilities need easy access to complete data to respond to customer questions and issues. Hexing billing system provides customer information management (CIS). Also, this system support grid management function, archive management which record all related information of customers, and of course Generating bills according to the customer consumption; maintain historical information regarding services, accounts, and customers; track and verify consumption to facilitate billing process; and more from one comprehensive application.

Key benefits

• Process all metered and non-metered billing functions quickly, easily and accurately.
• Support more than one million residential and industrial customers.
• Evaluating the customer’s requirement and finalizing the contract.
• Also handling contract management such as cancellation, termination, and customization.
• Evaluating and finalizing results in order to issuing the bill.
• Integration through the CIM standard with other 3^rd party system such as AMI…. etc.

Background

Being not costly distribution transformers, utility companies don’t care that big number of outage potentials. Losing each distribution transformer normally at the pick time will reduce total revenue as well as customer satisfaction while cost-effective monitoring of such transformers provides live tracking to prevent any transformer failure.

Solution Overview

Hexing’ Transformer Monitoring System (TMS) is designed based on state-of-the-art multi-functional gateway which accurately measures electrical parameters of transformer’ LV side, manages belonging smart PLC or RF residential meters (as a DCU) and monitor transformer’ oil or even control relevant feeder/transformer ( up to 800A).

This advanced TMS unit has 2 types for the cases that utility wants to monitor the transformer and manage smart meters or monitor transformer, manage smart meters with extra ability of remote switching. Basic unit measures secondary side of transformer via portable Rogowski CTs and advanced type does same measurement but via normal split-core CTs installed in the box. Collected load, network and oil data will be securely transferred to the utility over GPRS/3G/4G or even Ethernet cable.

Except asset management that is the main concern of Hexing TMS, there are other applications like peak shaving, loss monitoring (a key tool of ATC&C system) and Feeder monitoring, all to optimize smart grid structure.

Solution Overview

Hexing develops a mature loss management platform ATC&C (Aggregate Technical, Commercial & Collection) to monitor, locate and analysis a combination of different technical and non-technical losses. It represents overall and individual losses based on 4 different resources (feeder, transformer area, voltage level & zone). In case there is no access to some metering nodes over lack of communication channel in meter, an advanced HHU can collect data and immediately transfer to HES over cellular 3G/4G network.

ATC&C system is representing revenue protection concept over 3 mature individual platforms:

• Technical loss based on fixed elements of network equipment and following calculation methods like lines and transformers
• Commercial loss based on almost all kind of non-technical loss like tampers, faulty meters, incorrect readout & etc.
• Collection loss based on overdue or any missing of electricity bill.

This platform developed for several applications that are common resources of loss in all distribution networks like distribution lines, distribution transformers, boundary areas, current transformers and end-user AMR/AMI meters.

Key Benefits

• Effectively enhancing utilities investment capabilities
• Accurate demand planning
• Tamper reduction
• Outage risks reduction
• Efficient asset management

Background

Utility companies have different customers that categorized based on required demand. End user customers mostly divided into two groups, Residential and Industrial customers that residential customers are huge in number but small in revenue in comparison to commercial and industrial (C&I) customer which are few in number but they are big in revenue. Utilities always face many challenges to monitor those big customers for example, Illegal tamper causes high commercial losses, it is difficult to make a field visit and inspection, Delayed bill payment brings high bad debt, and High asset fail risk in case of over loading (transformer).

Overview

Hexing smart C&I metering solution integrates a broad portfolio of devices, IT hardware and software to block revenue leakage along the power distribution chain. The architecture is comprised of three layers:

Layer 1 – Low Voltage Side: Hexing designed smart meter and enclosure with complete anti-tamper facilities. And also developed a prepayment solution for small C&I customer with external breaker to disconnect power supply whenever the credit is run off.

Layer 2- Median Voltage Side: In the MV side, Hexing provides integrated metering solution with combined CT/PT devices. MV metering suit installed at the primary side of transformer makes it difficult for end user to touch and perform any illegal manipulation.

Layer 3- Master Station: Hexing C&I solution includes a multi-vendor HES, it supports interaction with MDM, CIS and other legacy system.
