2015 Annual Report 1

1. INTRODUCTION

The Power Quality Committee (PQC) was formed based on the recommendations of 2004 PQ

Workshop held at Riyadh in March, 2004. The PQC is a permanent committee with members

from major industries, academic institutions and electricity utilities. PQC Chairman is

appointed through an internal election by the Power Quality Committee members.

One of the important recommendations of the 2004 PQ Workshop was to publishing an

annual report dealing with the existing PQ levels across National Grid SA transmission

networks and its relative impacts on the bulk industrial customers. The aim of the desired

annual report is to:

Exchange information of PQ related issues.

Extract lessons learnt from discussing disturbances and fault incidents reported by

National Grid SA and by bulk customers.

Develop PQ database identifying records of disturbances and their effects upon the

operation of their major industrial customers specifically Saudi Aramco and SABIC

companies.

Recommend follow up actions so that secure supply system and high quality of power

supply can be verified.

The purpose of implementing the work is to coordinate between all PQC members,

information and experiences exchange, and to highlight the guidelines and roadmaps that can

help secure acceptable level of power supply to end users.

The PQC meets on a regular basis to discuss the PQ issues and case studies and formulate the

future plans. During the year of 2015, PQC members had scheduled four meetings and a

Power Quality Workshop. These are useful where PQ related topics are discussed, recent

customer or research oriented PQ studies and projects have been demonstrated, and follow up

actions and recommendations are reviewed.

2. MISSIONS AND OBJECTIVES

PQC exchanges information and technical data and unify procedures related to PQ issues in

the Kingdom on a regular basis. The Committee forms a good interconnection tool between

SEC and its subsidiaries, the major bulk customers (Saudi Aramco and SABIC), academia and

research institutes and regulatory authorities. Electrical System Supply disturbances that cause

bulk customer's mis-operation or loss of power supply and production are recorded and

analyzed. Identifying and following causes of disturbances and providing recommendations to

enhance the performance of the supplying systems are also part of the group activities.

The main objectives of the PQC are:

Reporting Disturbances

The performance of the supplying system will be identified throughout reporting

disturbances that affect the operation of the bulk customers with the transmission

networks. Any event in the power systems, that results in deviation of the supply

system voltage from and emergency (±10%) conditions are planned to be collected.


Identifying PQ Problems

Analysis tools will be executed to identify disturbances, its origin and causes. This will

be useful in providing suitable remedy action to reduce the possibility of disturbance

occurrence.

Recommend Follow up actions

Following the analysis, procedures and certain recommendations might be stated for

specific remedy actions to be followed.

Enhance coordination between all parties

Coordination between all parties is one of the PQC objectives. Coordination between

transmission supplying system capabilities and bulk customer's needs, exchange of

information and experiences, and scheduled meetings between all parties will be useful

to verify the maximum secure operating conditions and decrease the possibility of

disturbance re-occurrence.

Handle PQ database

Finally, National Grid SA is handling the PQ parametrs database (for previous years)

required for the evaluation in the PQC annual disturbance report.

3. PQC MEMBERS

contributes to 10% of the disturbances. Around 6% of the reported incidents were caused by

Protection Related Problem. The highest number of incidents that affected Saudi Aramco

occurred during April and May (refer to Figure 6.5).

As evident from Figure 6.4, in the case of SABIC, the most common cause is the Equipment

Failure (34%) and Generation Impact (33%). Other significant contributors for SABIC are

IPP/IWPP, Human Error and System Deficiency (all around 11%). The highest number of

incidents that affected SABIC occurred in January (refer to Figure 6.6).

6.3 Disturbance Records – Voltage Levels

The reliability / availability of the transmission network provided by National Grid SA should

also be taken into considerations when evaluating National Grid SA – Customers nature of

disturbances. Major bulk customers are generally supplied power at different transmission

voltage levels (380, 230, 132, and 115 kV levels).

Table 6.1 shows the record of disturbances for the year 2015 classified as per voltage levels .

The majority of the fault incidents that affect the operation system in Saudi Aramco are due to

disturbances within the 115 kV transmission networks (84% of the interruptions are due to

115 kV faults). On the other hand, majority of the SABIC disturbances are due to faults at the

380 kV transmission systems (67% of the interruptions are due to 380 kV faults) even though

the number of interruptions is low.

Figure 6.7 and 6.8 give the graphical view of the disturbances for Saudi Aramco and SABIC

respectively or the year 2015.

as intensive maintenance processes and inspection tests at the interrupted locations that may

result in decreasing the possibility of disturbances recurrences.

Among the different disturbance locations, the highest interruption frequency of occurrence

that affected Saudi Aramco was reported in southern part of EOA (Shedgum, Ain Dar,

Uthmaniyah, Hawiyah, Dhahran and Abqaiq) where 61 % of the total disturbances originated.

Moreover, a significant 36 % of the total disturbances originated from northern area of EOA

(Khursaniyah, Berri, Juaymah, Abu Ali, Safaniyah, Khafji and Jadidah). On the other hand,

Jubail area and Rabigh are the main disturbance locations affected SABIC where

approximately 44% and 33% of the total disturbances originated respectively.

Table 6.2 and 6.3 shows the list of disturbances locations that affected Saudi Aramco and

SABIC respectively for the year 2015. Figure 6.9 and 6.10 give the graphical view of the

7. KEY PERFORMANCE INDICATORS – KPIS

The Key Performance Indices (KPIs) are universally used to evaluate the performance of a

power system and its component units. They are the basic management tools serving to

identify potential system weaknesses and improvement needs.

The performance indices empower the concerned organizations for active participation in the

planning process and undertaking timely corrective measures for necessary rectifications and

system improvement actions, eventually leading to accomplishing a better customer service

target.

The assessment of system performance is a valuable procedure for important reasons: 1) It

establishes the chronological changes in system performance and helps to identify weaknesses

and areas of reinforcement, 2) It establishes existing indices which serve as a guide for

acceptable values in future reliability assessments, and 3) It enables previous predictions to be

compared with actual operating experience.

Customer Average Interruption Duration Index (CAIDI) and Voltage Dip (VD) KPIs are

chosen for tracking supply performance of Saudi Aramco and SABIC.

7.1 Customer Average Interruption Duration Index

The Customer Average Interruption Duration Index (CAIDI) is a reliability index used by

electric power utilities. It is related to the duration of the interruptions when the supply is off

and the number of the experienced interruption incidents. CAIDI is measured in minutes

according to the following formula.

𝑪𝑨𝑰𝑫𝑰 =𝑺𝒖𝒎 𝒐𝒇 𝒂𝒍𝒍 𝒊𝒏𝒕𝒆𝒓𝒓𝒖𝒑𝒕𝒊𝒐𝒏 𝒅𝒖𝒓𝒂𝒕𝒊𝒐𝒏𝒔

𝑻𝒐𝒕𝒂𝒍 𝒏𝒖𝒎𝒃𝒆𝒓 𝒐𝒇 𝒊𝒏𝒕𝒆𝒓𝒓𝒖𝒑𝒕𝒊𝒐𝒏 𝒊𝒏𝒄𝒊𝒅𝒆𝒏𝒕𝒔

Customer Average Interruption Duration Index for the Saudi Aramco and SABIC is presented

in Figure 6.11 for the years 2010-2015.

7.2 Voltage Dips

Voltage dip is reduction in voltage, 10% to 90% of nominal, typical lasting from cycles to

seconds. Voltage dips are caused by abrupt increase in loads such as faults, motor starting,

switching of furnaces, or they are caused by abrupt increase in source impedance caused by

interruption elements.

Number of voltage dips that affected Saudi Aramco and SABIC are shown in Figure 6.12 for

the years 2010-2015.
