    1. INTRODUCTION

    Transelectrica is the only one transmission and

    system operator in Romania and administrates the

    transmission network. Transelectrica, coordinator for

    the Smart Grids implementation project in Romania,

    has a sustained investment plan for modernizing and

    strengthening the transmission system, as of 2010, 44%

    of its 79 substations have already gone through this

    process. Transelectrica Metering Branch OMEPA is the

    first class A Metering Operator for Wholesale

    Electricity Market (WEM) and is interest in developing

    the integrated online monitoring systems for metering

    and PQ monitoring, according with Transelectricas

    Metering and Power Quality monitoring stategy during

    2011-2020 [1].

    According with The Electricity Transmission

    power grid- Technical code [2] TSO has performed the

    following PQ necessary steps:

    In 2006, after metering system was operational, the first temporary and then first permanent PQ

    monitoring systems were dedicated to the PQ

    monitoring of the interface between TSO - DSO and

    TSO EC;

    Since 2006 TSOs specialists attended PQ working meeting and were involved in the Leonardo

    Power Quality Initiative Vocational Education System

    (LPQIVES) training programs. At present they are

    certified Power Quality 1st / 2

    nd Degree Experts [3];

    In 2007 the WEM has been total liberalized and the third PQ monitoring systems has been dedicated to

    the OMEPA permanent monitoring at the interface

    between TSO and EC.

    In 2007 Electricity Regulatory Authority

    (ANRE) issued The Electricity Transmission Power

    gridStandard of performance [4] including more PQ

    aspects from international standards EN 50160, CEI

    61000-4-30 and, since then, TSO has performed the

    following PQ necessary steps:

    In 2008 TSO has approved its own PQ Policy, taking under consideration the Voltage Quality,

    Continuity of Supply and Commercial Quality;

    In 2008 Institute Study Design Engineering, Romania, designed for Transelectrica the study Fezability Study and Tender Specification for

    development a system for integrating the existing

    PQMS [5];

    In 2009 ANRE has issued the Technical Regulations named "Technical conditions for the

    connection of wind power plants to electricity grids of

    public interest, completing the Technical Code for

    the Electricity Transmission Grid and the Technical

    Code for the Electricity Distribution Grid [6];

    In 2010 the Action Plan for implementation in the national power system of the Smart Grid concept

    has been approved by the Ministry of Economy,

    Commerce and Business Environment. The aim of the

    plan is to set a roadmap towards implementation of the

    smart grid concept, starting from feasibility studies and

    requisite legislation.

    In 2011 according to TSOs PQ strategy, has been implemented The system for integrating the

    existing PQMS, according with the new standards,

    upgrading the instruments and the communication

    infrastructure [5];

    In 2011 Transelectrica Metering Branch OMEPA

    has issued a Technical Regulation regarding the

    metering and power quality instruments cod NTI-TEL-

    M-002-2011-00. New instruments were purchased in
